The Video Home System〔(IEEE History Center: Development of VHS ), cites the original name as "Video Home System", from an article by Yuma Shiraishi, one of its inventors. Retrieved December 28, 2006.〕 (VHS) is a standard for consumer-level use of analog recording on videotape cassettes. It was developed by Victor Company of Japan (JVC) in the 1970s. 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 VCRs as having the power to disrupt their business, while television users viewed the VCR as the means to take control of their hobby.〔Glinis, Shawn Michael. "VCRs: The End of TV as Ephemera." University of Wisconsin-Milwaukee, May 2015. Web. 09 Oct. 2015.〕 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, succeeding as the dominant home video format throughout the tape media period.〔(【引用サイトリンク】title=Lessons Learned from the VHS – Betamax War )〕 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.〔(''"Parting Words For VHS Tapes, Soon to Be Gone With the Rewind"'' ), Washington Post, August 28, 2005.〕 By 2008 DVD had achieved mass acceptance and replaced VHS as the preferred method of distribution.〔(HREF="url=http://www.latimes.com/entertainment/news/la-et-vhs-tapes22-2008dec22,0,5852342.story ">title=VHS era is winding down ) )〕 Often considered an important medium of film history, the influence of VHS on art and cinema was highlighted in a retrospective staged at the Museum of Arts and Design in 2013. In 2015 the Yale University Library collected nearly 3,000 horror and exploitation movies on VHS tapes, distributed from 1978 to 1985, calling them "the cultural id of an era."〔(【引用サイトリンク】website=American Libraries Magazine )〕 == History == 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「VHS」の詳細全文を読む スポンサード リンク
