The Video Home System (VHS) is a standard for consumer-level analog video recording on tape cassettes. Developed by Victor Company of Japan (JVC) in the early 1970s, it was released in Japan in late 1976 and in the USA in early 1977.

From the 1950s, magnetic tape video recording became a major contributor to the television industry, via the first commercialized video tape recorders (VTRs). At that time, the devices were used only in expensive professional environments such as television studios and medical imaging (fluoroscopy). In the 1970s, videotape entered home use, creating the home video industry and changing the economics of the television and movie businesses. The television industry viewed videocassette recorders (VCRs) as having the power to disrupt their business, while television users viewed the VCR as the means to take control of their hobby.

In the 1980s and 1990s, at the peak of VHS's popularity, there were videotape format wars in the home video industry. Two of the formats, VHS and Betamax, received the most media exposure. VHS eventually won the war; dominating 60 percent of the North American market by 1980 and succeeding as the dominant home video format throughout the tape media period.

Optical disc formats later began to offer better quality than analog consumer video tape such as standard and super-VHS. The earliest of these formats, LaserDisc, was not widely adopted. However, after the introduction of the DVD format in 1997, VHS's market share began to decline. By 2008, DVD had achieved mass acceptance and replaced VHS as the preferred low end method of distribution.
