M is the name of a professional analog videocassette format created around 1982 by Matsushita and RCA. Developed as a competitor to Sony's Betacam format, M used the same videocassette (and the same oxide-formulated magnetic tape stock) as VHS, much the same way that Betacam was designed to take advantage of cheap and readily available Betamax videocassettes,
