How many people own video cassette recorders?

The Video Home System, better known by its abbreviation VHS, is a recording and playing standard for analog video cassette recorders (VCRs), developed by Victor Company of Japan, Limited, aka JVC, and launched in September 1976. There is a relatively popular belief that VHS officially stands for Video Home System. In fact it initially stood for Vertical Helical Scan, after the relative head/tape scan technique (making the popular version a backronym), some actually believe that it once stood for Video Head Set, due to the way the cassette's magnetic strip is read with a silver read head.
