The VCR was first introduced in July 1977 by JVC (V2000). It was rivaled by Betamax, which was released first(in November 1975). It only had two-hour and four-hour modes, however.
VHS technology was developed during the 1970s and the first units went on sale in the late 70's early 90's. Other commercial tape formats used by studios were available as far back as 1956.
