Sony had met with executives from Matsushita (now
Panasonic) in late 1974 and early 1975 to discuss the forthcoming home video market. Soon after, RCA met with executives from
JVC, at the time a Matsushita subsidiary, who had created another video format,
VHS. JVC refused to compromise the picture quality of their format by allowing a four-hour mode. Matsushita later met with RCA and agreed to manufacture a four-hour-capable VHS machine for RCA.
Picture quality When Betamax was introduced in Japan and the United States in 1975, its Beta I speed of 1.57 inches per second (ips) offered a higher horizontal resolution (approximately 250 lines vs 240 lines horizontal NTSC), lower video noise, and less luma/chroma
crosstalk than VHS, and was later marketed as providing pictures superior to VHS's playback. However, the introduction of Beta II speed, 0.79 ips (two-hour mode), to compete with VHS's two-hour Standard Play mode (1.31 ips) reduced Betamax's horizontal resolution to 240 lines.
Outcome Although Betamax initially owned 100% of the market in 1975 (as VHS did not launch until the following year) the perceived value of longer recording times eventually tipped the balance in favor of VHS. By 1980, VHS had proven favorable among consumers and was successful in controlling 60% of the North American market. By 1981, sales of Beta machines in the United States had sunk to 25% of the VCR market. As movie studios, video studios, and video rental stores turned away from Betamax, the combination of lower market share and a lack of available titles further weakened Betamax's position. ==Contributing factors==
