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. The most infamous of these was the videotape format war of the early 1980s, when Sony marketed the Betamax system for video cassette recorders against the VHS format developed by JVC. In the end, VHS gained critical mass in the marketplace and became the worldwide standard for consumer VCRs and Sony adopted the format. While Betamax is for all practical purposes an obsolete format, a professional-oriented component video format called Betacam that was derived from Betamax is still used today, especially in the film and television industry.

In 1968 Sony introduced the Trinitron brand name for its line of aperture grille cathode ray tube televisions and (later) computer monitors. Trinitron displays are still produced, but only for markets such as Pakistan, Bangladesh, India and China. Sony discontinued the last Trinitron-based television set in the USA in early 2007. Trinitron computer monitors were discontinued in 2005.

Sony launched the Betamax videocassette recording format in 1975. In 1979 the Walkman brand was introduced, in the form of the world's first portable music player.

1982 saw the launch of Sony's professional Betacam videotape format and the collaborative Compact Disc format. 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 a lot of 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. In 1983 Sony launched the MSX, a home computer system, and introduced the world (with their counterpart Philips) to the Compact Disc or CD. In 1984 Sony launched the Discman series which extended their Walkman brand to portable CD products. In 1985 Sony launched their Handycam products and 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 Discman

In addition to developing consumer-based recording media, after the launch of the CD Sony began development of commercially based recording media. In 1986 they launched Write-Once optical discs (WO) and in 1988 launched Magneto-optical discs which were around 125MB size for the specific use of archival data storage.[14]
