The 8mm video format refers informally to three related videocassette formats. These are the original Video8 ( analog recording ) format and its improved successor Hi8 ( analog video and analog audio but with provision for digital audio ), as well as a more recent digital recording format known as Digital8 . Their user base consisted mainly of amateur camcorder users, although they also saw important use in the professional television production field.

89-792: In 1982, five companies – Sony , Matsushita (now Panasonic) , JVC , Hitachi , and Philips – created a preliminary draft of the unified format and invited members of the Electronic Industries Association of Japan, the Magnetic Tape Industry Association, the Japan Camera Industry Association and other related associations to participate. As a result, a consortium of 127 companies endorsed 8-mm video format in April 1984. In January 1984, Eastman Kodak announced

178-417: A helical-scan head drum (it having a small 40mm head) to read from and write to the magnetic tape. The drum rotates at high speed (one or two rotations per picture frame—about 1800 or 3600 rpm for NTSC, and 1500 or 3000 rpm for PAL) while the tape is pulled along the drum's path. Because the tape and drum are oriented at a slight angular offset, the recording tracks are laid down as parallel diagonal stripes on

267-664: A 70 percent share of the market when it decided to pull the plug on the format in 2010. Sony still develops magnetic tape storage technologies along with IBM , and are one of only two manufacturers of Linear Tape-Open (LTO) cartridges. In 1998, Sony launched the Memory Stick format, the flash memory cards for use in Sony lines of digital cameras and portable music players. It has seen little support outside of Sony's own products, with Secure Digital cards (SD) commanding considerably greater popularity. Sony has made updates to

356-453: A Super Famicom with a built-in CD-ROM drive, named the "Play Station" (also known as SNES-CD ). However, a day after the announcement at CES, Nintendo announced that it would be breaking its partnership with Sony, opting to go with Philips instead but using the same technology. The deal was broken by Nintendo after they were unable to come to an agreement on how revenue would be split between

445-783: A completely separate financial entity owned by Sony, so as to retain the project and maintain relationships with Philips for the MMCD development project (which helped lead to the creation of the DVD ) In 2021, the WIPO 's annual review of the World Intellectual Property Indicators report ranked Sony's as ninth in the world for the number of patent applications published under the PCT System . 1,793 patent applications were published by Sony during 2020. This position

534-465: A flip-up screen meant for video playback and limited recording. These have been adapted for Digital8 as well as MiniDV formats, even as portable DVD players have become popular in this application. Such players saw use in professional applications, particularly with airlines, which, during the 1980s, adopted 8mm as the format for in-flight movies . They remained in use among some airlines until at least 2015. Among home and amateur videographers, Video8/Hi8

623-457: A focus on reducing the major losses from the television business. In February 2014, Sony announced the sale of its Vaio PC division to a new corporation owned by investment fund Japan Industrial Partners and spinning its TV division into its own corporation as to make it more nimble to turn the unit around from past losses totaling $ 7.8 billion over a decade. Later that month, they announced that they would be closing 20 stores. In April,

712-513: A format war with DVD-Audio . Still, neither gained a major foothold with the general public. CDs had been preferred by consumers because of the ubiquitous presence of CD drives in consumer devices until the early 2000s when the iPod and streaming services became available. In 2015, Sony introduced LDAC , a proprietary audio coding technology which allows streaming high-resolution audio over Bluetooth connections at up to 990 kbit/s at 32 bit/96 kHz. Sony also contributed it as part of

801-533: A hard-shell cassette. These cassettes share similar size and appearance with the audio cassette , but their mechanical operation is far closer to that of VHS or Betamax videocassettes. Standard recording time is up to 90 minutes for PAL and 120 minutes for NTSC. These times are doubled for Long Play (LP) recording mode. (The cassette holds the same length tape; tape consumption is different between PAL and NTSC recorders.) Longer tapes were available, but were less common. Like most other videocassette systems, Video8 uses

890-399: A life insurance company in 1979, one of its many peripheral businesses. Amid a global recession in the early 1980s, electronics sales dropped and the company was forced to cut prices. Sony's profits fell sharply. "It's over for Sony", one analyst concluded. "The company's best days are behind it." Around that time, Norio Ohga took up the role of president. He encouraged the development of

979-450: A mode called "PCM Multi Audio Recording". While other 8mm decks support only a single stereo PCM recording, these units provide five additional stereo PCM tracks that are recorded in the video area of the signal. This allows 8mm tapes to hold 6 parallel tracks of audio, each up to 4 hours long (in LP mode). Only one stereo track can be recorded or listened to at a time, and tracks are selected with

1068-573: A powerful exporter during the 1960s, 1970s and 1980s, supplying the U.S. Military with bomb parts used in the Vietnam War . It also helped to significantly improve American perceptions of "made in Japan" products. Known for its production quality, Sony was able to charge above-market prices for its consumer electronics and resisted lowering prices. In 1971, Masaru Ibuka handed the position of president over to his co-founder Akio Morita. Sony began

1157-449: A similar dual-deck machine. Ultimately, Video8's main rival in the camcorder market turned out to be VHS-C, with neither dominating the market completely. However, both formats (along with their improved descendants, Hi8 and S-VHS-C) were nevertheless very successful. Collectively, they dominated the camcorder market for almost two decades before they were eventually crowded out by digital formats, such as MiniDV , 8cm DVD . To counter

1246-731: A slogan known as "make.believe" in 2009. Despite some successes, the company faced continued struggles in the mid- to late-2000s. In 2012, Kazuo Hirai was promoted to president and CEO, replacing Stringer. Shortly thereafter, Hirai outlined his company-wide initiative, named "One Sony" to revive Sony from years of financial losses and bureaucratic management structure, which proved difficult for former CEO Stringer to accomplish, partly due to differences in business culture and native languages between Stringer and some of Sony's Japanese divisions and subsidiaries. Hirai outlined three major areas of focus for Sony's electronics business, which include imaging technology, gaming and mobile technology, as well as

1335-408: A subsidiary and, at the same time, a holding company for Sony's music businesses, along with SMEJ . Television lines Television lines ( TVL ) is a specification of an analog camera or monitor's horizontal image resolution . The TVL is one of the most important resolution measures in a video system. The TVL can be measured with the standard EIA 1956 resolution chart . TVL is defined as

1424-441: A tape-protecting mechanism built into the shell. Unlike the ones on VHS and VHS-C shells, which consist of only a single piece of plastic that protects the part of the tape that is read by the player/recorder, Hi8's tape-protection mechanism consists of two pieces of plastic at the top of the shell that come together and form a casing that protects both sides of the tape, and a latch that prevents this casing from opening and exposing

1513-590: A television of at least 55 inches (140 centimeters) with a price higher than $ 2,500 as well as second largest TV brand by market share and, as of 2020, the third largest television manufacturer in the world by annual sales figures. Although not being a part of any traditional keiretsu , Sony has a weak tie to the Sumitomo Mitsui Financial Group (SMFG), which traces its roots to the Mitsui zaibatsu . This connection dates back to

1602-640: A while; but by 2005 only Sony sold Digital8 consumer equipment. Digital8's main rival is the consumer MiniDV format, which uses narrower tape and a correspondingly smaller cassette shell. Since both technologies share the same logical audio/video format, Digital8 can theoretically equal MiniDV or even DVCAM in A/V performance. But by the year 2005, Digital8 had been relegated to the entry-level camcorder market. Digital8 recordings are not interchangeable with analog recordings , although many models of Digital8 equipment are able to play Hi8/Video8 analog recordings. By 2009,

1691-570: A wholly owned subsidiary through a takeover bid. On 1 April 2021, Sony Corporation was renamed Sony Group Corporation. On the same day, Sony Mobile Communications Inc. absorbed Sony Electronics Corporation, Sony Imaging Products & Solutions Inc., and Sony Home Entertainment & Sound Products Inc. and changed its trade name to Sony Corporation. Sony has historically been notable for creating its own in-house standards for new recording and storage technologies, instead of adopting those of other manufacturers and standards bodies, while its success in

1780-580: Is a Japanese multinational conglomerate headquartered in Minato, Tokyo , Japan. The Sony Group comprises entities such as Sony Corporation , Sony Semiconductor Solutions , Sony Entertainment (including Sony Pictures and Sony Music Group ), Sony Interactive Entertainment , Sony Financial Group , and others. Sony was established in 1946 as Tokyo Tsushin Kogyo by Masaru Ibuka and Akio Morita . This electronics company, known for creating products such as

1869-453: Is in the quality of the tape itself, but the main differences lie in the encoding of the video when it is recorded onto the tape. Video8 was the earliest of the three formats, and is entirely analog. The 8mm tape width was chosen as smaller successor to the 12mm Betamax format, using similar technology (including U-shaped tape loading) but in a smaller configuration in response to the small configuration VHS-C compact camcorders introduced by

1958-505: Is largely offered in two forms, either chips embedded in smartphones or plastic cards with chips embedded in them. Sony plans to implement this technology in train systems across Asia. In 2019, Sony launched the ELTRES, the company's proprietary low-power wide-area wireless communication ( LPWAN ) standard. Until 1991, Sony had little direct involvement with the video game industry. The company supplied components for other consoles, such as

2047-443: Is organized into the following business segments: Game & Network Services (G&NS), Music, Pictures, Electronics Products & Solutions (EP&S), Imaging & Sensing Solutions (I&SS), Financial Services, and Others. Usually, each business segment has a handful of corresponding intermediate holding companies under which all the related businesses are folded into, such as Columbia Records being part of Sony Music Group ,

2136-402: Is recorded along a narrow linear track at the edge of the tape, where it is vulnerable to damage. Coupled with the slow horizontal tape speed, the sound was comparable with that of a low-quality audio cassette. By contrast, all Video8 machines used audio frequency modulation (AFM) to record sound along the same helical tape path as that of the video signal. This meant that Video8's standard audio

2225-573: Is up from their previous ranking as 13th in 2019 with 1,566 applications. Best known for its electronic products, Sony offers a wide variety of product lines in many areas. At its peak, it was dubbed as a "corporate octopus", for its sprawling ventures from private insurance to chemicals to cosmetics to home shopping to a Tokyo-based French food joint, in addition its core businesses such as electronics and entertainment. Even after it has unwound many business units including Sony Chemicals and Vaio PC, Sony still runs diverse businesses. As of 2020, Sony

2314-579: The ATRAC brand, against the more widely used MP3. Until late 2004, Sony's Network Walkman line of digital portable music players did not support the MP3 standard natively. In 2004, Sony built upon the MiniDisc format by releasing Hi-MD . Hi-MD allows the playback and recording of audio on newly introduced 1 GB Hi-MD discs in addition to playback and recording on regular MiniDiscs. In addition to saving audio on

2403-824: The Android Open Source Project starting from Android 8.0 " Oreo ", enabling every OEM to integrate this standard into their own Android devices freely. However the decoder library is proprietary , so receiving devices require licenses. On 17 September 2019, the Japan Audio Society (JAS) certified LDAC with their Hi-Res Audio Wireless certification. Currently the only codecs with the Hi-Res Audio Wireless certification are LDAC and LHDC , another competing standard. Sony demonstrated an optical digital audio disc in 1977 and soon joined hands with Philips, another major contender for

2492-635: The Crystal LED Display. Sony used the Compact Cassette format in many of its tape recorders and players, including the Walkman , the world's first portable music player. Sony introduced the MiniDisc format in 1992 as an alternative to Philips DCC or Digital Compact Cassette and as a successor to the Compact Cassette. Since the introduction of MiniDisc, Sony has attempted to promote its own audio compression technologies under

2581-535: The Video8 format . Video8 and the follow-on hi-band Hi8 format became popular in the consumer camcorder market. In 1987 Sony launched the 4 mm DAT or Digital Audio Tape as a new digital audio tape standard. Sony held a patent for its proprietary Trinitron until 1996. Sony introduced the Triluminos Display, the company's proprietary color reproduction enhancing technology, in 2004, featured in

2670-536: The "PCM Multi Audio" selector button. Introduced in 1999, Digital8 is a form of the industry standard DV codec , recorded on Hi8 media. In engineering terms, Digital8 and MiniDV are indistinguishable at the logical format level. To store the digitally encoded audio/video on a standard NTSC Video8 cassette, the tape must be run at double the Hi8 speed. Thus, a 120-minute NTSC Hi8 tape yields 60 minutes of Digital8 video. Most Digital8 units offer an LP mode, which increases

2759-454: The "door" is open and in the "SAVE" position when it is closed. (Not all tape cases have markings for this information.) The tape can only be recorded onto (or recorded over) when this tab is in the "REC" position. This is an improved version of the VHS write-protect tab, which prevents erasure after it has been broken off, requiring covering with adhesive tape or filling with an obstruction to remove

2848-603: The 1950s when it was the only bank the company dealt with. Sony is listed on the Tokyo Stock Exchange (in which it is a constituent of the Nikkei 225 and TOPIX Core30 indeces) with an additional listing in the form of American depositary receipts listed in the New York Stock Exchange (traded since 1961, making it one of the oldest Japanese company to be listed on an American exchange), and

2937-542: The 3 inches (7.6 cm) of monitor height is used rather than the 4 inches (10 cm) of whole monitor width). TVL is an inherent quality of a camera or monitor, influenced by the visual bandwidth of the transmission system used. It should not be confused with the number of horizontal scanning lines of such systems, which e.g. 625 lines for the PAL system, 525 lines for the NTSC system. Since analog transmission of video

3026-512: The ATF system was that unlike in the case of a control track, an 8mm camera or player cannot keep track of where the tape is during fast forward and rewind (though it could during shuttle search). This made editing using a linear editing system problematic. Some later cameras and players attempted to derive the tape position from the differential rotation of the spools with limited success. As with many other video cassette formats, 8mm videocassettes have

3115-519: The CCD-M8, which at one kilogram was half the mass of the CCD-V8, though it had no zoom and supported only manual focus with three focus settings. In April 1986 six Japanese electronics companies—Matsushita, Hitachi, Pentax, Minolta, Mitsubishi, Sharp and Toshiba—announced their lack of plans to embrace eight millimeter in the foreseeable future and instead adopted VHS-C format. Yet, several months later at

3204-523: The Memory Stick format with Memory Stick Duo and Memory Stick Micro . The company has also released USB flash drive products, branded under the Micro Vault line. Sony introduced FeliCa , a contactless IC card technology primarily used in contactless payment , as a result of the company's joint development and commercialization of Near-Field Communication (NFC) with Philips. The standard

3293-406: The U.S. market and launched the new industry of consumer microelectronics." By the mid-1950s, American teens had begun buying portable transistor radios in huge numbers, helping to propel the fledgling industry from an estimated 100,000 units in 1955 to 5 million units by the end of 1968. Sony co-founder Akio Morita founded Sony Corporation of America in 1960. In the process, he was struck by

3382-515: The audio recording systems of their base formats; VHS HiFi Stereo outperforms Video8/Hi8 AFM, but was rarely available on camcorders. In the late 1980s, digital (PCM) audio was introduced into some higher-grade models of Hi8 recorders. Hi8 PCM audio operates at a sampling rate of 32 kHz with 8-bit samples and DBX dynamic range expansion. This was higher fidelity than the monaural linear dubbing offered by VHS/S-VHS camcorders. PCM-capable Hi8 recorders can simultaneously record PCM stereo in addition to

3471-412: The board. Eventually, Sony President Ohga decided to retain the project after being reminded by Kutaragi of the humiliation he suffered from Nintendo. Nevertheless, due to strong opposition from a majority present at the meeting as well as widespread internal opposition to the project by the older generation of Sony executives, Kutaragi and his team had to be shifted from Sony's headquarters to Sony Music ,

3560-496: The compact disc (CD) in the 1970s and 1980s, and of the PlayStation in the early 1990s. Ohga went on to purchase CBS Records in 1988 and Columbia Pictures in 1989, greatly expanding Sony's media presence. Ohga would succeed Morita as chief executive officer in 1989. Under the vision of co-founder Akio Morita and his successors, the company had aggressively expanded into new businesses. Part of its motivation for doing so

3649-572: The company announced that they would be selling 9.5 million shares in Square Enix (roughly 8.2 percent of the game company's total shares) in a deal worth approximately $ 48 million. In May 2014 the company announced it was forming two joint ventures with Shanghai Oriental Pearl Group to manufacture and market Sony's PlayStation game consoles and associated software in China. In 2015, Sony purchased Toshiba's image sensor business. It

3738-425: The company's struggling media businesses, encouraging blockbusters such as Spider-Man while cutting 9,000 jobs. He hoped to sell off peripheral business and focus the company again on electronics. Furthermore, he aimed to increase cooperation between business units, which he described as "silos" operating in isolation from one another. In a bid to provide a unified brand for its global operations, Sony introduced

3827-409: The competition. It was followed by Hi8, a version with improved resolution. Although this was still analog, some professional Hi8 equipment could store additional digital stereo PCM sound on a special reserved track. Digital8 is the most recent 8mm video format. It retains the same physical cassette shell as its predecessors, and can even record onto Video8 (not recommended) or Hi8 cassettes. However,

3916-469: The discs, Hi-MD allows the storage of computer files such as documents, videos and photos. In 1993, Sony challenged the industry standard Dolby Digital 5.1 surround sound format with a newer and more advanced proprietary motion picture digital audio format called SDDS (Sony Dynamic Digital Sound). This format employed eight channels (7.1) of audio opposed to just six used in Dolby Digital 5.1 at

4005-487: The early years owes to a smooth capitalization on the Digital Compact Cassette standard introduced by Philips , with which Sony went on to enjoy a decades-long technological relationship in various areas. Sony (either alone or with partners) has introduced several of the most popular recording formats, including the 3.5-inch floppy disk , compact disc and Blu-ray disc. Sony introduced U-matic ,

4094-523: The film studio. According to one report, Sony was set to make a final decision on the possibility of the merger of the TV, film, & gaming businesses by the end of its fiscal year in March of the following year (2017). In 2017, Sony sold its lithium-ion battery business to Murata Manufacturing . In 2019, Sony merged its mobile, TV and camera businesses. On 1 April 2020, Sony Electronics Corporation

4183-424: The financial sector. In 2021, Sony transformed into a holding company, handing over the name Sony Corporation to its subsidiary as the electronics company. Sony, with its 55 percent market share in the image sensor market, is the largest manufacturer of image sensors, the second largest camera manufacturer, and is among the semiconductor sales leaders. It is the world's largest player in the premium TV market for

4272-465: The format in which video is encoded and stored on the tape itself is the entirely digital DV format (and thus very different from the analog Video8 and Hi8). Some Digital8 camcorders support Video8 and Hi8 with analog sound (for playback only), but this is not required by the Digital8 specification. In all three cases, a length of 8mm-wide magnetic tape is wound between two spools and contained within

4361-553: The global market, which required labeling their products with a short and easy brand name. While looking for a romanized name, they at first strongly considered using their initials, TTK. The primary reason they did not is that the railway company Tokyo Kyuko was known as TTK. The company occasionally used the syllabic acronym "Totsuko" in Japan, but during his visit to the United States, Morita discovered that Americans had trouble pronouncing that name. Another early name that

4450-481: The head mistracked. The system automatically adjusted the tracking such that the two frequencies produced were of equal magnitude. This system was derived from the dynamic track following (DTF) used by the Philips Video 2000 system. Sony rechristened the system as automatic track following (ATF) as the 8mm system lacked the ability of the heads to physically move within the head drum. The main disadvantage of

4539-540: The introduction of the Super-VHS format, Sony introduced Video Hi8 (short for high-band Video8 ). First demonstrated in February 1989, it was initially endorsed by ten other manufacturers — Aiwa, Canon, Fuji, Hitachi, Konica, Matsushita, Maxell, Ricoh, Sanyo and TDK. Like S-VHS, Hi8 uses improved recorder electronics and media formulation to increase the recorded bandwidth of the luminance signal. The luminance carrier

4628-434: The legacy (analog AFM) stereo audio tracks. All Hi8 equipment can record and play in the legacy Video8 format. The reverse is not usually the case though there are a few late-entry Video8 systems that recognize and play Hi8 recordings. Besides the brands listed above, Hi8 equipment was also offered by Nikon, Samsung, Sharp and TEAC. The Sony EV-S900 (Hi8), Sony EV-S800, Sony EV-S700U, and Pioneer VE-D77 (Video8) all support

4717-520: The marketbase and became the worldwide standard for consumer VCRs. Betamax is, for all practical purposes, an obsolete format. Sony's professional-oriented component video format called Betacam , which was derived from Betamax, was used until 2016 when Sony announced it was stopping production of all remaining 1/2-inch video tape recorders and players, including the Digital Betacam format. In 1985, Sony launched their Handycam products and

4806-466: The maximum number of alternating light and dark vertical lines that can be resolved per picture height. A resolution of 400 TVL means that 200 distinct dark vertical lines and 200 distinct white vertical lines can be counted over a horizontal span equal to the height of the picture. For example, on 4 by 3 inches (10.2 cm × 7.6 cm) monitor with 400 TVL, 200 vertical dark lines can be counted over 3 inches (7.6 cm) width on monitor (Note that

4895-420: The mobility of employees between American companies, which was unheard of in Japan at that time. When he returned to Japan, he encouraged experienced, middle-aged employees of other companies to reevaluate their careers and consider joining Sony. The company filled many positions in this manner, and inspired other Japanese companies to do the same. Moreover, Sony played a major role in the development of Japan as

4984-728: The new technology in the U.S. In 1985, Sony of Japan introduced the Handycam , one of the first Video8 cameras with commercial success. Much smaller than the competition's VHS and Betamax video cameras, Video8 became very popular in the consumer camcorder market. Video8 was launched in 1984, into a market dominated by the VHS-C and Betamax formats. The first two models were the Kodak Kodavision 2200 and 2400, both over US$ 1,500. The Kodak machines were produced by Matsushita Electric, but Matsushita itself had shown no interest in selling

5073-470: The palm of the user's hand. This was impossible with Betamax and full-sized VHS camcorders, with all of them having shoulder-mount form factor. Video8 also has an advantage in terms of recording and playback time over VHS-C – 180 minutes vs 45 minutes in SP mode for standard cassettes for each format. Video8/Hi8's main drawback is that tapes made with Video8 camcorders cannot be played on VHS hardware. Instead it

5162-460: The popularity of the analog 8mm formats had dwindled considerably and new camcorders that support the format were unobtainable, having been superseded by digital formats, mainly MiniDV and 8 cm DVD . These in turn have been largely displaced by high-definition camcorders that record to flash storage cards. Both Video8 and Hi8 blank media remain available and affordable but are increasingly rare. Tape-based camcorders are still readily available in

5251-459: The recording time on an NTSC P6-120 tape to 90 minutes. For PAL, the Digital8 recorder runs 1½ times faster; thus, a 90-minute PAL Hi8 tape yields 60 minutes of Digital8 video. PAL LP mode returns the tape speed to the Hi8 SP speed, so a Hi8 90-minute tape yields 90 minutes of Digital8 video. Sony has licensed Digital8 technology to at least one other firm (Hitachi), which marketed a few models for

5340-521: The same product under its own name. The first Sony camcorder capable of recording to standard 8mm videotape was the Sony CCD-V8, with 6x zoom but only manual focus, released in 1985 with an MSRP of approximately $ 1,175, ($ 3,329 in 2023) and a mass of 1.97 kg. The same year, Sony released the CCD-V8AF which added autofocus. Also in 1985, Sony released the first of their compact Handycam range:

5429-590: The secondhand market. The last Hi8 camcorder (the Sony CCD-TRV238) and the last Digital8 camcorder (the Sony DCR-TRV285) were both discontinued in 2007, ending the 8mm format's 22 years on the market. The three formats are physically very similar, featuring both the same magnetic tape width and near-identical cassette shells, measuring 95 × 62.5 × 15 mm. This gives a measure of backward compatibility in some cases. One difference between them

5518-662: The sound chip for the Super Famicom from Nintendo , and operated a video game studio, Sony Imagesoft . As part of a joint project between Nintendo and Sony that began as early as 1988, the two companies worked to create a CD-ROM version of the Super Famicom, though Nintendo denied the existence of the Sony deal as late as March 1991. At the Consumer Electronics Show in June 1991, Sony revealed

5607-598: The specific use of archival data storage, in 1986 and 1988 respectively. In the early 1990s, two high-density optical storage standards were being developed: one was the MultiMedia Compact Disc (MMCD), backed by Philips and Sony, and the other was the Super Density Disc (SD), supported by Toshiba and many others. Philips and Sony abandoned their MMCD format and agreed upon Toshiba's SD format with only one modification. The unified disc format

5696-572: The storage technology, to establish a worldwide standard. In 1983, the two company jointly announced the Compact Disc (CD). In 1984, Sony launched the Discman series, an expansion of the Walkman brand to portable CD players. Sony began to improve performance and capacity of the novel format. It launched write-once optical discs (WO) and magneto-optical discs which were around 125MB size for

5785-420: The summer 1986 Consumer Electronics Show Olympus introduced an eight-millimeter camcorder manufactured by Matsushita, and Hitachi was reported to be making eight-millimeter machines for Minolta & Pentax. In terms of video quality, Video8 offers similar performance to Beta-II and VHS in their standard-play modes. In terms of audio, Video8 generally outperforms its older rivals. Audio on Standard VHS and Beta

5874-401: The tape. The heads on the drum of a Video8 recorder move across the tape at (a writing speed of) 3.75 meters per second. Unlike preceding systems, 8mm did not use a control track on the tape to facilitate the head following the diagonal tracks. Instead 8mm recorded a sequence of four sine waves on each video track such that adjacent tracks would produce one of two heterodyne frequencies if

5963-403: The tape. The playback/recording unit can depress this latch to open the casing and gain access to the tape. To prevent the recording on the tape from being erased, there is a small write-protect tab that can be moved to one of two positions, labeled "REC" and "SAVE" (sometimes marked as "ERASE ON" and "OFF", respectively). Comparing the sliding tab to a door, the tape is in the "REC" position when

6052-505: The technologies developed for the company's optical disc products. In 1983, Sony introduced 90 mm micro diskettes, better known as 3.5-inch (89 mm) floppy disks , which it had developed at a time when there were 4" floppy disks, and many variations from different companies, to replace the then on-going 5.25" floppy disks. Sony had great success and the format became dominant. 3.5" floppy disks gradually became obsolete as they were replaced by current media formats. Sony held more than

6141-515: The time. Ultimately, SDDS has been vastly overshadowed by the preferred DTS ( Digital Theatre System ) and Dolby Digital standards in the motion picture industry. SDDS was solely developed for use in the theatre circuit; Sony never intended to develop a home theatre version of SDDS. Sony and Philips jointly developed the Sony-Philips digital interface format ( S/PDIF ) and the high-fidelity audio system SACD . The latter became entrenched in

6230-422: The transistor radio TR-55 , the home video tape recorder CV-2000 , the portable audio player Walkman , and the compact disc player CDP-101 , embarked on diverse business ventures. In 1988, Sony acquired CBS Records , and in 1989, it acquired Columbia Pictures . The company also introduced the home video game console PlayStation in 1994, which was the first of the eponymous brand . In Japan, Sony expanded into

6319-491: The two companies. The breaking of the partnership infuriated Sony President Norio Ohga , who responded by appointing Kutaragi with the responsibility of developing the PlayStation project to rival Nintendo. At that time, negotiations were still on-going between Nintendo and Sony, with Nintendo offering Sony a "non-gaming role" regarding their new partnership with Philips. This proposal was swiftly rejected by Kutaragi who

6408-455: The world's first LED-backlit LCD televisions. It was widely used in other Sony's products as well, including computer monitors, laptops, and smartphones. In 2013, Sony released a new line of televisions with an improved version of the technology, which incorporated quantum dots in the backlight system. It was the first commercial use of quantum dots. In 2012, the company revealed a prototype of an ultrafine RGB LED display, which it calls

6497-518: The world's first videocassette format, in 1971, but the standard was unpopular for domestic use due to the high price. The company subsequently launched the Betamax format in 1975. Sony was involved in the videotape format war of the early 1980s, when they were marketing the Betamax system for video cassette recorders against the VHS format developed by JVC . In the end, VHS gained critical mass in

6586-412: The write protection. Efforts were made to expand Video8 from only the camcorder market into mainstream home video. But as a replacement for full-size VCRs, Video8 failed. It lacks the long (5+ hours) recording times of both VHS and Betamax, offers no clear audio/video improvement, and cost more than equivalent full-size VCRs. Even with all of the advanced features offered in high-end Video8 machines, there

6675-564: Was a loan word in Japanese, which connoted smart and presentable young men, which Akio Morita and Masaru Ibuka considered themselves to be. The first Sony-branded product, the TR-55 transistor radio , appeared in 1955, but the company name did not change to Sony until January 1958. At the time of the change, it was extremely unusual for a Japanese company to use Roman letters to spell its name instead of writing it in kanji . The move

6764-453: Was assumed that the camcorder would be directly plugged into one's TV. Although it is possible to transfer tapes (using the VCR to rerecord the source video as it is played back by the camcorder), the VHS copy would lose some quality compared to the 8mm original. During the 1990s Sony did market a few VHS VCRs that also feature an 8mm deck to allow convenient transfer to VHS. GoldStar also made

6853-525: Was called DVD and was introduced in 1997. Sony was one of the leading developers of the Blu-ray optical disc format, the newest standard for disc-based content delivery. The first Blu-ray players became commercially available in 2006. The format emerged as the standard for HD media over the competing format, Toshiba's HD DVD , after a two-year-long high-definition optical disc format war . Sony's laser communication devices for small satellites rely on

6942-477: Was established as an intermediate holding company to own and oversee its electronics and IT solutions businesses. On 19 May 2020, the company announced that it would change its name to Sony Group Corporation as of 1 April 2021. Subsequently, Sony Electronics Corporation would be renamed to Sony Corporation. On the same day the company announced that it would turn Sony Financial Holdings (currently Sony Financial Group), of which Sony already owns 65.06% of shares, to

7031-546: Was facing increasing criticism over his work with regard to entering the video game industry from within Sony. Negotiations officially ended in May 1992 and in order to decide the fate of the PlayStation project, a meeting was held in June 1992, consisting of Sony President Ohga, PlayStation Head Kutaragi and several senior members of Sony's board. At the meeting, Kutaragi unveiled a proprietary CD-ROM-based system he had been working on which involved playing video games with 3D graphics to

7120-513: Was joined by Akio Morita to establish a company called Tokyo Tsushin Kogyo ( 東京通信工業 , Tōkyō Tsūshin Kōgyō , Tokyo Telecommunications Engineering Corporation) . The company built Japan's first tape recorder , called the Type-G. In 1958, the company changed its name to "Sony". Tokyo Tsushin Kogyo founders Morita and Ibuka realized that to achieve success and grow, their business had to expand to

7209-422: Was no compelling reason to switch to Video8 for the home application. Initially, many movies were prerecorded in 8mm format for home and rental use, but the rental market for Video8 never materialized. Sony maintained a line of Video8 home VCRs well into the 1990s, but unlike VHS, 8mm VCRs with timers were very expensive. Sony also produced a line of Video8 Walkman -branded players and recorders, with and without

7298-414: Was not without opposition: TTK's principal bank at the time, Mitsui , had strong feelings about the name. They pushed for a name such as Sony Electronic Industries, or Sony Teletech. Akio Morita was firm, however, as he did not want the company name tied to any particular industry. Eventually, both Ibuka and Mitsui Bank's chairman gave their approval. According to Schiffer, Sony's TR-63 radio "cracked open

7387-478: Was of a far higher quality than that of its rivals. Early Video8 camcorders used mono AFM sound, but this was later made stereo. This cost less than including 8mm's optional digital stereo audio track. Linear audio did have the advantage that (unlike either AFM system) it could be re-recorded without disturbing the video, doing this in 8mm required a deck that supported digital audio. The small size of media means that many Video8 camcorders are small enough to hold in

7476-618: Was popular enough for Sony to make equipment for video editing and production. The format also saw some use in professional electronic news gathering and electronic field production . Hi8 tapes were also used for an 8-track professional digital audio format called DTRS , including the Tascam DA-88 and similar models. While the cassettes are physically interchangeable, these recordings are not interchangeable with 8mm video formats. Sony Sony Group Corporation (formerly Tokyo Tsushin Kogyo K.K. and Sony Corporation )

7565-578: Was ranked 88th on the 2021 Fortune Global 500 list. In 2023, the company was ranked 57th in the Forbes Global 2000 . Sony began in the wake of World War II. In 1946, Masaru Ibuka started an electronics shop in Shirokiya, a department store building in the Nihonbashi area of Tokyo . The company started with a capital of ¥190,000 and a total of eight employees. On 7 May 1946, Ibuka

7654-483: Was reported in December 2016 by multiple news outlets that Sony was considering restructuring its U.S. operations by merging its TV & film business, Sony Pictures Entertainment, with its gaming business, Sony Interactive Entertainment. According to the reports, such a restructuring would have placed Sony Pictures under Sony Interactive's CEO, Andrew House, though House would not have taken over day-to-day operations of

7743-433: Was shifted from 4.2 MHz for regular 8-mm up to 5.7 MHz for Hi8, and the frequency deviation was increased to 2 MHz from the 1.2 MHz of standard 8-mm. Both Hi8 and S-VHS were officially rated at a luminance resolution of 400 lines , a vast improvement from their respective base formats and are roughly equal to LaserDisc quality. Chrominance resolution for both remain unchanged. Both S-VHS and Hi8 retain

7832-492: Was the pursuit of "convergence", linking film, music and digital electronics via the Internet. This expansion proved unrewarding and unprofitable, threatening Sony's ability to charge a premium on its products as well as its brand name. In 2005, Howard Stringer replaced Nobuyuki Idei as chief executive officer, marking the first time that a foreigner had run a major Japanese electronics firm. Stringer helped to reinvigorate

7921-471: Was tried out for a while was "Tokyo Teletech" until Akio Morita discovered that there was an American company already using Teletech as a brand name. The name "Sony" was chosen for the brand as a mix of two words: one was the Latin word " sonus ", which is the root of sonic and sound, and the other was " sonny ", a common slang term used in 1950s America to call a young boy. In 1950s Japan, "sonny boys"
