Not all video tape recorders use a cassette to contain the videotape. Early models of consumer video tape recorders , and most professional broadcast analog videotape machines (e.g. 1-inch Type C) use reel to reel tape spools. The history of the videocassette recorder follows the history of videotape recording in general.
A 14-inch reel of 2-inch quad videotape compared with a modern-day MiniDV videocassette. Both media store one hour of color video. The first commercial professional broadcast quality videotape machines capable of replacing kinescopes were the two-inch quadruplex videotape (Quad) machines introduced by Ampex on April 14, 1956, at the National Association of Broadcasters convention in Chicago.
The number of video tape recorders continued to increase during the late 1960s, leading to the EIAJ-1 standard for 1 ⁄ 2-inch tape on a 7 inch reel. The follow-up EIAJ-2 built the take-up reel into the recorder body. In September 1971, Sony introduced the U-matic format, aimed at professional users, which replaced the open reels with a cassette.

Tapes of 45 minutes or less contained 20-micrometre (0.79-mil) thickness tape. The mechanically complicated recorders themselves also proved somewhat unreliable.
