Videotape is first demonstrated at the 1956 NARTB (now NAB) convention in Chicago, Illinois. It was the demonstation of the first practical and commercially successful format called 2" Quadruplex.More here.
The first practical professional videotape machines were the Quadruplex machines introduced by Ampex in the United States in 1956. Quad employed a transverse (scanning the tape across its width) four-head system on a two-inch (5.08 cm) tape, and linear heads for the soundtrack. The BBC experimented with a high-speed linear videotape system called VERA, but this was ultimately unfeasible, it used 1/2 inch (1.27 cm) tape traveling at 200 inches (5.08 m) per second.
