Betamax
Betamax (also known as Beta, and stylized as the Greek letter β in its logo) is a discontinued consumer analog videocassette recording format developed by Sony. It was one of the main competitors in the videotape format war against its primary rival, VHS. Betamax was introduced in Japan on May 10, 1975, and launched in the United States later that year.
Betamax was widely regarded, in part due to Sony's marketing, as offering superior picture quality compared to VHS. Its initial β1 speed provided 250 horizontal lines of resolution, compared to VHS's 240 lines, but early Beta tapes were limited to 60 minutes of recording time, making them impractical for recording movies or sporting events. To address this, Sony introduced the β2 speed, which doubled recording time to two hours but reduced resolution, negating its technical advantage.
VHS's commercial success over Betamax was also driven by JVC's strategy of licensing the format broadly, spurring competition and lowering prices among manufacturers. In contrast, Sony initially resisted licensing Beta, limiting its market reach. By the late 1980s, Betamax’s decline was evident, and in 1988 Sony tacitly acknowledged defeat when it announced it would add VHS models to its videocassette recorder (VCR) lineup.
Despite losing the format war, Sony continued producing Betamax recorders until August 2002 and sold blank Beta cassettes until March 2016, marking the end of the format’s commercial lifespan.
