(Video Home System) A half-inch, analog videocassette recorder (VCR) format introduced by JVC in 1976 to compete with Sony's Betamax, introduced a year earlier. Its ability to record an entire movie caused it to supersede sales of Betamax units for the home market almost immediately. By 1980, VHS had 70% of the video recording market and became the standard for consumer entertainment as well as for industry training and product promotions.
S-VHS (Super VHS) was a subsequent format that increased resolution from 240 to 400 lines, but was not widely used by consumers. In 2002, sales of VHS players were superseded by DVD players for the first time. See Betamax, helical scan, D-VHS and VTR.
