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

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.[2][3]

In January 1984, Eastman Kodak announced the new technology in the U.S.[4][5] 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.
