Sony introduced [[U-matic]], the world's first [[videocassette]] format, in 1971, but the standard was unpopular for domestic use due to the high price.<ref>{{Cite web |date=20 January 2018 |title=U-matic (1971 – 1990s) |url=https://obsoletemedia.org/u-matic/ |access-date=5 August 2020 |website=Museum of Obsolete Media |language=en-GB |archive-date=2020-10-31  |archive-url=https://web.archive.org/web/20201031103303/https://obsoletemedia.org/u-matic/ |url-status=live }}</ref> The company subsequently launched the [[Betamax]] format in 1975.<ref>{{Cite news |last=Curtis |first=Sophie |date=10 November 2015 |title=Sony is finally killing off Betamax video tapes |language=en-GB |work=Daily Telegraph |url=https://www.telegraph.co.uk/technology/sony/11986020/Sony-is-finally-killing-off-Betamax-video-tapes.html |archive-url=https://ghostarchive.org/archive/20220110/https://www.telegraph.co.uk/technology/sony/11986020/Sony-is-finally-killing-off-Betamax-video-tapes.html |archive-date=10 January 2022 |url-access=subscription |url-status=live |access-date=4 January 2019 |issn=0307-1235}}{{cbignore}}</ref> 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]].<ref name=":2">{{Cite web |title=The History of Format Wars and How Sony Finally Won...

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.<ref>{{Cite web |date=28 May 2014 |title=Digital Betacam (1993–2016) |url=https://obsoletemedia.org/digital-betacam/ |access-date=7 January 2019 |website=Museum of Obsolete Media |language=en-GB |archive-date=2020-06-12  |archive-url=https://web.archive.org/web/20200612113414/https://obsoletemedia.org/digital-betacam/ |url-status=live }}</ref>

In 1985, Sony launched their [[Handycam]] products and the [[8 mm video format|Video8 format]].<ref>{{Cite web |date=27 May 2014 |title=Video8 (1985 – 2000s) |url=https://obsoletemedia.org/video8/ |access-date=4 January 2019 |website=Museum of Obsolete Media |language=en-GB |archive-date=2020-12-10  |archive-url=https://web.archive.org/web/20201210165127/https://obsoletemedia.org/video8/ |url-status=live }}</ref> Video8 and the follow-on hi-band [[8 mm video format|Hi8]] format became popular in the consumer camcorder market. In 1987 Sony launched the 4&nbsp;mm DAT or [[Digital Audio Tape]] as a new digital audio tape standard.<ref>{{Cite web |date=10 October 2014 |title=What's DAT Sound? |url=https://blogs.library.duke.edu/bitstreams/2014/10/10/dat-sound/ |access-date=4 January 2019 |website=Bitstreams: The Digital Collections Blog |language=en-US |archive-date=2020-10-30  |archive-url=https://web.archive.org/web/20201030143758/https://blogs.library.duke.edu/bitstreams/2014/10/10/dat-sound/ |url-status=live }}</ref>
