VHS meaning in Computing ?

VHS (Video Home System) is a standard for consumer-level analog video recording on tape cassettes.

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 expensive devices were used only in 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 motion picture and television businesses. The television industry viewed videocassette recorders (VCRs) as having the power to disrupt their business, while television users viewed the VCR as a means to take control of their viewing experiences.

In the later 1970s and early 1980s, there was a format war in the home video industry. Two of the standards, VHS and Betamax, received the most media exposure. VHS eventually won the war, dominating 60 percent of the North American market by 1980 and emerging 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 VHS and S-VHS. The earliest of these formats, LaserDisc, was not widely adopted across Europe, but was hugely popular in Japan and a minor success in the United States. After the introduction of the DVD format in 1996, however, the market share for VHS began to decline. In 2003, DVD rentals surpassed those of VHS in the United States and by 2008, DVD had replaced VHS as the preferred low-end method of distribution. The last known company in the world to manufacture VHS equipment (VCR/DVD combos), Funai of Japan, ceased production in July 2016, citing shrinking demand and difficulties procuring parts.
