DOS is a family of disk operating systems, hence the name. DOS consists of MS-DOS and a rebranded version under the name IBM PC DOS, both of which were introduced in 1981. Other compatible systems from other manufacturers include DR-DOS, ROM-DOS, PTS-DOS, FreeDOS. MS-DOS dominated the x86-based IBM PC compatible market between 1981 and 1995. Dozens of other operating systems use the acronym "DOS", including the mainframe DOS/360 from 1966. Others are Apple DOS, Apple ProDOS, Atari DOS, Commodore DOS, TRSDOS, AmigaDOS. Fictional operating systems have used this acronym as well, such as GLaDOS from the video game Portal. IBM PC DOS and its predecessor, 86-DOS, resembled Digital Research's CP/M—the dominant disk operating system for 8-bit Intel 8080 and Zilog Z80 microcomputers—but instead ran on Intel 8086 16-bit processors; when IBM introduced the IBM PC, built with the Intel 8088 microprocessor, they needed an operating system. Seeking an 8088-compatible build of CP/M, IBM approached Microsoft CEO Bill Gates.
IBM was sent to Digital Research, a meeting was set up. However, the initial negotiations for the use of CP/M broke down. Digital Research founder Gary Kildall refused, IBM withdrew. IBM again approached Bill Gates. Gates in turn approached Seattle Computer Products. There, programmer Tim Paterson had developed a variant of CP/M-80, intended as an internal product for testing SCP's new 16-bit Intel 8086 CPU card for the S-100 bus; the system was named QDOS, before being made commercially available as 86-DOS. Microsoft purchased 86-DOS for $50,000; this became Microsoft Disk Operating System, MS-DOS, introduced in 1981. Within a year Microsoft licensed MS-DOS to over 70 other companies, which supplied the operating system for their own hardware, sometimes under their own names. Microsoft required the use of the MS-DOS name, with the exception of the IBM variant. IBM continued to develop their version, PC DOS, for the IBM PC. Digital Research became aware that an operating system similar to CP/M was being sold by IBM, threatened legal action.
IBM responded by offering an agreement: they would give PC consumers a choice of PC DOS or CP/M-86, Kildall's 8086 version. Side-by-side, CP/M cost $200 more than PC DOS, sales were low. CP/M faded, with MS-DOS and PC DOS becoming the marketed operating system for PCs and PC compatibles. Microsoft sold MS-DOS only to original equipment manufacturers. One major reason for this was. DOS was structured such that there was a separation between the system specific device driver code and the DOS kernel. Microsoft provided an OEM Adaptation Kit which allowed OEMs to customize the device driver code to their particular system. By the early 1990s, most PCs adhered to IBM PC standards so Microsoft began selling MS-DOS in retail with MS-DOS 5.0. In the mid-1980s Microsoft developed a multitasking version of DOS; this version of DOS is referred to as "European MS-DOS 4" because it was developed for ICL and licensed to several European companies. This version of DOS supports preemptive multitasking, shared memory, device helper services and New Executable format executables.
None of these features were used in versions of DOS, but they were used to form the basis of the OS/2 1.0 kernel. This version of DOS is distinct from the released PC DOS 4.0, developed by IBM and based upon DOS 3.3. Digital Research attempted to regain the market lost from CP/M-86 with Concurrent DOS, FlexOS and DOS Plus with Multiuser DOS and DR DOS. Digital Research was bought by Novell, DR DOS became Novell DOS 7. Gordon Letwin wrote in 1995 that "DOS was, when we first wrote it, a one-time throw-away product intended to keep IBM happy so that they'd buy our languages". Microsoft expected; the company planned to over time improve MS-DOS so it would be indistinguishable from single-user Xenix, or XEDOS, which would run on the Motorola 68000, Zilog Z-8000, LSI-11. IBM, did not want to replace DOS. After AT&T began selling Unix, Microsoft and IBM began developing OS/2 as an alternative; the two companies had a series of disagreements over two successor operating systems to DOS, OS/2 and Windows.
They split development of their DOS systems as a result. The last retail version of MS-DOS was MS-DOS 6.22. The last retail version of PC DOS was PC DOS 2000, though IBM did develop PC DOS 7.10 for OEMs and internal use. The FreeDOS project began on 26 June 1994, when Microsoft announced it would no longer sell or support MS-DOS. Jim Hall posted a manifesto proposing the development of an open-source replacement. Within a few weeks, other programmers including Pat Villani and Tim Norman joined the project. A kernel, the COMMAND. COM command line interpreter, core utilities were created by pooling code they had wri
COMDEX was a computer expo trade show held in the Las Vegas Valley of Nevada, USA, each November from 1979 to 2003. It was one of the largest computer trade shows in the world second only to the German CeBIT, one of the largest trade shows in any industry sector. COMDEX exhibitions were held in many other countries with 185 shows altogether; the first COMDEX was held in 1979 with 167 exhibitors and 3904 attendees. In 1981, the first COMDEX/Spring was held in New York City. COMDEX was started by The Interface Group, whose organizers included Sheldon Adelson, Robert Lively and Richard Katzeff. In 1995, they sold the show to the Japanese technology conglomerate Softbank Corp. In 2001, Softbank sold the show to a spin-off of Ziff Davis. After entering Chapter 11 bankruptcy in February 2003, Key3Media resurfaced as Medialive International with a cash infusion from Thomas Weisel Capital Partners, which had invested in the company. In November 2006, Forbes magazine reported that United Business Media PLC had purchased the events assets of MediaLive International Inc.
COMDEX was restricted to those directly involved in the computer industry. It was the one show where all levels of manufacturers and developers of computers, software and accessories met with distributors, retailers and their competitors. Colloquially known as "Geek Week", COMDEX evolved into a major technical convention, with the industry making major product announcements and releases there. Numerous small companies from around the world rose to prominence following appearance at COMDEX, industry leaders sought opportunities to make keynote addresses, they discussed the computer industry, history and future potential. The first COMDEX Conference, attracted 4000 paying attendees and grew to over 100,000, becoming a launch platform for key technologies. Bluetooth and USB had conference programming and associated exhibition floor pavilions to help these technologies and start up companies be seen in such a large event and marketplace. In 1999, Linus Torvalds attended the exhibition to talk about the Linux family of operating system.
A Linux conference and exhibition hall was a co-located event, helping elevate the open source products. In the late 1980s, COMDEX was opened to the general public, causing an explosion in attendance, but diluting COMDEX's wholesale industry focus. Retailers and consultants complained that'leading edge' customers, upon whom they relied for early adoption of new technology, were buying products at'show specials' and expecting the dealers to support those products.. The broadening of audience criteria came about as IT departments decentralized and purchasing of technology products shifted from a central corporate IT budget to departments and company divisions, mirroring the shift from mainframes to decentralized networks and local area networking, the Internet as the corporate backbone. After the Spring 1981 show in New York City and 1982 in Atlantic City, COMDEX began regular spring shows in Atlanta, Georgia from 1983 through 1988. Alternated sites between Atlanta and Chicago; the final Atlanta Spring COMDEX was held in 1997.
The first COMDEX show outside the US was held in Amsterdam 1982. In the record years 1998 and 2000, 21 exhibitions were arranged yearly all over the World: Europe, Africa and other parts of America. 69% of the 185 shows took place outside the US. When the US shows were cancelled, they kept on for short time, e.g. Gothenburg and São Paulo 2004 and the last in Athens in November 2005; the decline occurred globally: the 2000 show in Basel with 1400 exhibitors drew 79000 attendees, but 2001 17% less. Following COMDEX Fall 1999, organizers made major changes to their criteria for admission of mass media, adjusting criteria to accommodate bloggers with significant market reach, but restricting simple and open access to anyone declaring themselves'media', it offered regular public attendance for the general public. In 2000, major companies such as IBM, Compaq decided to discontinue their involvement with COMDEX to allocate resources more efficiently through their own corporate events or other direct-to-consumer selling, the dot-com bubble caused a decline on the IT market.
To reduce costs following the market downturns after the 9/11 attacks many would-be exhibitors stopped renting out or scaled back official COMDEX booths on the convention center floors, set up invitation-only suites in various Las Vegas hotels. This allowed exhibitors to concentrate their efforts on industry attendees rather than the general public. COMDEX/Fall 2001 organizers at Los Angeles-based Key3Media Group Inc. said they expected attendance to fall from the previous year's 200,000 to 150,000. They expected the number of exhibitors to decline from 2,350 to 2,000 and the square footage of exhibitor space to slide from just over 1 million to 750,000; the last Las Vegas show in November 2003 attracted 40,000 visitors. In June 2004, COMDEX cancelled the 2004 exhibition in Las Vegas making the Consumer Electronics Show its replacement in Las Vegas. By 2004 the personal computer had become a commodity item priced at levels individual departments and consumers overall could buy without needing much corporate oversight, so "computers" became just one of many products in the consumer electronics channels and the Consumer Electronics Show.
A COMDEX event was designed to exist only on the internet without a physical meeting location. It was announced to com
Sony Music Entertainment Japan
Sony Music Entertainment Inc. abbreviated as SMEJ or SME, known as Sony Music Japan for short, is Sony's music arm in Japan. SMEJ is directly owned by Sony Corporation and independent from the United States-based Sony Music Entertainment due to its strength in the Japanese music industry, its subsidiaries including the Japanese animation production enterprise, established in September 1995 as a joint-venture between Sony Music Entertainment Japan and Sony Pictures Entertainment Japan, but which in 2001 became a wholly owned subsidiary of Sony Music Entertainment Japan. It was prominent in the early to mid'90s producing and licensing music for animated series such as Roujin Z from acclaimed Japanese comic artist Katsuhiro Otomo and Capcom's Street Fighter animated series; until March 2007, Sony Music Japan had its own North American sublabel, Tofu Records. Releases of Sony Music Japan now appear on Columbia Records and/or Epic Records in North America. Sony does not have the trademark rights to the Columbia name in Japan, so releases under Columbia Records from another country appears on Sony Records in Japan, but retains the usage of the "walking eye" logo.
The Columbia name and trademark is controlled by Nippon Columbia, which was, in fact, the licensee for the American Columbia Records up until 1968 though relations were severed as far back as World War II. Nippon Columbia does not have direct relations with the British Columbia Graphophone Company, so the licensee for the British Columbia Graphophone Company was Toshiba Musical Industries. With Sony Corporation of America's buyout of Bertelsmann's stake in Sony BMG, Sony Music Entertainment Japan stepped in to acquire outstanding shares of BMG Music Japan from Sony BMG, making it a wholly owned subsidiary of Sony Music Japan. Sony Music Entertainment Japan was incorporated in March 1968 as a Tokyo-based 50/50 joint venture between Sony Corporation and U. S. conglomerate CBS to distribute the latter's music releases in Japan. The company was incorporated with Sony co-founder Akio Morita as president. Norio Ohga was part of the management team from the formation of the company and served as president and representative director since April 1970.
In 1972, when CBS/Sony was generating robust profits, Ohga was named chairman and at the same time gained further responsibility and influence within Sony. He would continue to work for the music company one morning a week. In 1980, Toshio Ozawa succeeded Ohga as president. In 1983, the company was renamed CBS/Sony Group. In January 1988, after more than a year of negotiations, Sony acquired CBS Records and the 50% of CBS/Sony Group that it did not own. In March 1988, four wholly owned subsidiaries were folded into CBS/Sony Group: CBS/Sony Inc. Epic/Sony Records Inc. CBS/Sony Records Inc. and Sony Video Software International. The company was renamed Inc.. Shugo Matsuo was named new president in January 1992, replacing Toshio Ozawa, appointed to the post of chairman. Overall sales for the fiscal year ending March 31, 1991 were 83.8 billion yen with a pretax profit of 9.2 billion yen. In June 1996, Ryokichi Kunugi became the new president. Shugo Matsuo was named chairman. Shigeo Maruyama was appointed to the new post of CEO on October 1, 1997 and replaced Kunugi as president in February 1998.
As of 2007, Naoki Kitagawa is the current CEO of the group. In May 2018, SMEJ acquired a 39% stake in the Peanuts comic strip franchise from DHX Media. Sony Music Entertainment announced the launch of its first video game publishing label, Unties, in October 2017. Unties will publish indie games for the PlayStation 4, PlayStation VR, Nintendo Switch, PC; the name was selected by Sony as representative of helping to "unleash" the power of independent video game development and "unshackle" such developers from the traditional video game publishing process. Unties’ first release was Tiny Metal, a turn-based tactics video game developed by Area 35, for the Nintendo Switch, PS4, PC; the game was first premiered at PAX West Indie Megabooth. Published Azure Reflections, a side-scrolling bullet hell developed by Souvenir Circ. on May 15 2018 for the PS4. Published Touhou Gensou Wanderers Reloaded, a roguelike rpg developed by Aqua Style, for the PS4, Nintendo Switch, PC. Published Necrosphere, a platformer developed by Cat Nigiri, for the PS4, Nintendo Switch, PC, PSVita.

A Video Floppy is an analog recording storage medium in the form of a 2-inch magnetic floppy disk used to store still frames of composite analog video. A video floppy known as a VF disk, could store up to 25 frames either in the NTSC or PAL video standards, with each frame containing 2 fields of interlaced video; the video floppy could store 50 frames of video, with each frame of video only containing one field of video information, recorded or played back in a "skip-field" fashion. Video floppies were first developed by Sony and introduced under the "Mavipak" name in 1981 for their Mavica still video camera; the video floppy format was used by Minolta and Canon for their still video cameras introduced in the mid-to-late 1980s, such as the Canon Xapshot from 1988. Besides still video cameras, stand-alone recorders & players were available for the VF format, that could record from or output a composite video signal, to or from an external source; some VF recorders had the feature of recording a couple of seconds of audio that accompanied each video frame.
The video floppy saw a lot of uses during its heyday in the 1980s and 1990s, besides being used for still video cameras. Many medical endoscopy and dentistry video systems, as well as industrial video borescopes & fiberscopes, used VF disks for storing video images for playback and study. Standalone VF recorders & players were used by television stations and video production studios as a still-store system for stills & graphics for use in a television production, or for on-air slides used for station identification or during technical difficulties. A similar sized disk was used by the Zenith Minisport laptop computer from 1989, digitally formatted for data storage; the Minisport could store up to 793 KB of information on 2-inch LT format disks called LT-1. Video floppy and LT-1 are not compatible, so media can not be interchanged between drives using video floppy or LT standards. An enhanced version of the VF format called Hi-VF was introduced in the late 1980s, providing higher resolution per video still than its predecessor.
It used higher-bandwidth video recording, much like S-VHS as compared to VHS, or Hi8 compared to Video 8. Still video camera Floppy disk Digicamhistory.com, which features several VF & HiVF cameras from the late 1980s & early 1990s
Sony Corporation is a Japanese multinational conglomerate corporation headquartered in Kōnan, Tokyo. Its diversified business includes consumer and professional electronics, gaming and financial services; the company owns the largest music entertainment business in the world, the largest video game console business and one of the largest video game publishing businesses, is one of the leading manufacturers of electronic products for the consumer and professional markets, a leading player in the film and television entertainment industry. Sony was ranked 97th on the 2018 Fortune Global 500 list. Sony Corporation is the electronics business unit and the parent company of the Sony Group, engaged in business through its four operating components: electronics, motion pictures and financial services; these make Sony one of the most comprehensive entertainment companies in the world. The group consists of Sony Corporation, Sony Pictures, Sony Mobile, Sony Interactive Entertainment, Sony Music, Sony/ATV Music Publishing, Sony Financial Holdings, others.
Sony is among the semiconductor sales leaders and since 2015, the fifth-largest television manufacturer in the world after Samsung Electronics, LG Electronics, TCL and Hisense. The company's current slogan is Be Moved, their former slogans were The One and Only, It's like.no.other and make.believe. Sony has a weak tie to the Sumitomo Mitsui Financial Group corporate group, the successor to the Mitsui group. Sony began in the wake of World War II. In 1946, Masaru Ibuka started an electronics shop in a department store building in Tokyo; the company started with a total of eight employees. In May 1946, Ibuka was joined by Akio Morita to establish a company called Tokyo Tsushin Kogyo; the company built Japan's first tape recorder, called the Type-G. In 1958, the company changed its name to "Sony"; when Tokyo Tsushin Kogyo was looking for a romanized name to use to market themselves, they considered using their initials, TTK. The primary reason they did not is that the railway company Tokyo Kyuko was known as TTK.
The company used the acronym "Totsuko" in Japan, but during his visit to the United States, Morita discovered that Americans had trouble pronouncing that name. Another early name, tried out for a while was "Tokyo Teletech" until Akio Morita discovered that there was an American company 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", the root of sonic and sound, the other was "sonny", a common slang term used in 1950s America to call a young boy. In 1950s Japan, "sonny boys" was a loan word in Japanese, which connoted smart and presentable young men, which Sony founders 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 unusual for a Japanese company to use Roman letters to spell its name instead of writing it in kanji; the move was not without opposition: TTK's principal bank at the time, had strong feelings about the name.
They pushed for a name such as Sony Teletech. Akio Morita was firm, however. Both Ibuka and Mitsui Bank's chairman gave their approval. According to Schiffer, Sony's TR-63 radio "cracked open 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 the mobility of employees between American companies, 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, inspired other Japanese companies to do the same. Moreover, Sony played a major role in the development of Japan as a powerful exporter during the 1960s, 1970s and 1980s.
It helped to 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 a life insurance company in 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 the Compact Disc in the 1970s and 1980s, of the PlayStation in the early 1990s. Ohga went on to purchase CBS Records in 1988 and Columbia Pictures in 1989 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 in
Sony Mobile Communications Inc. is a multinational telecommunications company founded on October 1, 2001 as a joint venture between Sony and Ericsson, headquartered in Tokyo and wholly owned by Sony. It was incorporated as Sony Ericsson Mobile Communications, headquartered in London, until Sony acquired Ericsson's share in the venture on February 16, 2012. Sony Mobile has development facilities in Lund, Sweden. At its peak in 2007, Sony Ericsson held a 9 percent global market share making it the fourth largest vendor at the time; as of 2017 Sony Mobile held 4.8 % in Europe and 16.3 % in Japan. Since the current ownership structure, Sony Mobile create Android-powered smartphones under the Xperia sub-brand name - it currently or developed tablet computers and fitness trackers, alongside accessories and software for the devices; the current flagship device is the Sony Xperia 1. Swedish company Ericsson had been making mobile cell phones since the 1980s, their first handheld device being the Hotline Pocket introduced in 1987.
In the United States, Ericsson partnered with General Electric in the early nineties as Ericsson Mobile Communications to establish a US presence and brand recognition. General Electric left the joint venture. Ericsson had decided to obtain chips for its phones from a single source—a Philips facility in New Mexico. On March 17, 2000, a fire at the Philips factory contaminated the sterile facility. Philips assured Nokia that production would be delayed for no more than a week; when it became clear that production would be compromised for months, Ericsson was faced with a serious shortage. Nokia had begun to obtain parts from alternative sources, but Ericsson's position was much worse as production of current models and the launch of new ones was held up. Ericsson, in the mobile phone market for decades, was the world's third largest cellular telephone handset maker at the time behind Nokia and Motorola, was struggling with huge losses and decreasing market share; this was due to this fire as well as its inability to produce cheaper phones or fashionably-designed phones like Nokia managed to do.
Speculation began about a possible sale by Ericsson of its mobile phone division, but the company's president, Kurt Hellström, said it had no plans to do so. Hellström said, "Mobile phones are a core business for Ericsson. We wouldn't be as successful if we didn't have phones". Sony was a marginal player in the worldwide mobile phone market with a share of less than 1 percent in 2000. By August 2001, the two companies had finalised the terms of the merger announced in April. Ericsson contributed a majority of the Ericsson Mobile Communications company, excluding a minor part spun off as Ericsson Mobile Platforms. Sony contributed its entire handset division; the company was to have an initial workforce of 3,500 employees. Sony Ericsson's strategy was to release new models capable of digital photography as well as other multimedia capabilities such as downloading and viewing video clips and personal information management capabilities. To this end, it released several new models which had built-in digital camera and colour screen which were novelties at that time - examples include the Sony Ericsson T610, the P800 UIQ smartphone, the K700 handset.
The joint venture continued to make bigger losses in spite of booming sales - however it paid off as Sony Ericsson made its first profit in 2003 and in the following years increased handset sales. The joint venture was regarded to have been a success. In 2005, Sony Ericsson introduced the K750i with a 2 megapixel camera, as well as its platform mate, the W800i, the first of the Walkman phones capable of 30 hours of music playback. In 2005, Sony Ericsson agreed to become the global title sponsor for the WTA Tour in a deal worth $88 million US dollars over 6 years; the women's pro tennis circuit was renamed the Sony Ericsson WTA Tour. Just over a month on June 7, it announced sponsorship of West Indian batsmen Chris Gayle and Ramnaresh Sarwan. In October 2005, Sony Ericsson presented the first mobile phone based on UIQ 3, the P990. In 2007, the company's first 5-Megapixel camera phone, the Sony Ericsson K850i, was announced followed in 2008 by the C905, the world's first 8.1-Megapixel camera phone.
At Mobile World Congress 2009, Sony Ericsson unveiled the first 12-Megapixel camera phone, named Satio. On January 2, 2009, Sony Ericsson announced in Stockholm that it would have some of its mobile phones made in India, that its two outsourcing partners and Foxconn would manufacture ten million mobile phones per year by 2009. CEO Miles Flint announced at a press conference held with India's communications minister Dayanidhi Maran in Chennai that India was one of the fastest growing markets in the world and a priority market for Sony Ericsson with 105 million users of GSM mobile telephones. Sony Ericsson's handset shipments fell from a high of 30.8m in Q4 1999 to only 8.1m in Q1 2003. The company had made net losses in six of the 15 quarters and seen its cash reserves shrink from €2.2bn to €599m, after taking a €375m cash injection from its joint owners. The eclipse of the Symbian operating system by Apple's iPhone, by Google's Android, has affected Sony Ericsson's position in the market; the company struggled following the launch of Apple's iPhone in the third quarter of 2007.
Sony Ericsson was overtaken by its South Korean rival LG Electronics in Q1 2008. Sony Ericsson's company's profits fell sig
Still video camera
A still video camera is a type of electronic camera that takes still images and stores them as single frames of video. They peaked in popularity in the late 1980s and can be seen as the predecessor to the digital camera. However, unlike the latter, the image storage in such cameras is based on analog- rather than digital- technology; the best known models include the Sony Mavica and Canon's Xapshot cameras. The most common design has an image sensor and basic processing hardware similar to that of a domestic analog camcorder. However, instead of storing consecutive frames on tape to form a moving image, a single frame is extracted from the output video signal and saved on a rotating magnetic disk. In playback, the disk is spun at the frame rate of the video system with the frame being read repeatedly; this produces a conventional video signal. The limitation is that the playback system is equivalent to the operation of a paused video recorder. Since the video is stored as a conventional video frame in a format such as NTSC or PAL, the resolution is limited to that of any other video.
And since the images are not stored digitally, transferring the photos to a computer requires a video capture card. Digicammuseum.com, featuring all still video cameras announced
