BBC Betamax videos-BBCB discovery
Betamax (also called Beta, as in its logo) is a consumer-level analog-recording and cassette format of magnetic tape for video. It was developed by Sony and was released in Japan on May 10, 1975. The first Betamax device introduced in the United States was the LV-1901 console, which included a 19-inch (48 cm) color monitor, and appeared in stores in early November 1975. The cassettes contain 0.50-inch-wide (12.7 mm) videotape in a design similar to that of the earlier, professional 0.75-inch-wide (19 mm), U-matic format. Betamax is obsolete, having lost the videotape format war to VHS. Despite this, Betamax recorders would not be discontinued until 2002, while new Betamax cassettes were available until March 2016, when Sony stopped making and selling them.
