Televeision stations had video tape starting in 1956 way before VCRs. Most classic video that was not on film was recorded on 2" quad. Nothing better then watching a spot break running on a Ampex ACR25. There are still a few "quad"s out there able to play the old tapes that have not yet been dubed to current formats. Quad was the longest running standard video tape format other then 3/4" 1956 to about 1985 some were used into the 90's. They were more or less only made by Ampex and RCA. Ampex invented the format and traded rights to RCA for recording color. There were different tape speeds and low and high band and very late in the game there was two channel sound added for stereo. The first few years of M-TV aired most of the music videos from ACR25 spot players. The best analog VTR ever made was the Ampex ATR1 it would play just about anything recorded on quad it could preroll in about 1 or 2 secs to full lock up.
