"Magnetic tape was first used for data storage in 1951. The tape device was called UNISERVO and was the main I/O device on the UNIVAC I computer. The effective transfer rate for the UNISERVO was about 7,200 characters per second. The tapes were metal and 1200 feet long (365 meters) and therefore very heavy."

1951 - Idea of playing games on TV sets and started

As early as 1951, a young 29-year old TV engineer named Ralph Baer worked at Loral, a TV company. His Chief Engineer, Sam Lackoff, asked him to Build the best television set in the world. Designing a TV set was an easy task for Ralph, and he wanted to add a new concept that his boss did not understand: playing games on the television set. The video game concept was born, but could not be implemented since the boss refused the idea. In September 1966, Ralph came back to his 1951 idea of playing games on TV sets and started building the first video game prototypes. Therefore, Ralph Baer is accordingly credited as the inventor of the video game.
