In between 1949 and 1950, "bouncing ball" program was created by Charley Adama for MIT's Whirlwind system. This program wasn't interactive but it was considered to be an announcement for the games to come soon. In 1951 February, Christopher Strachey worked towards running draughts or checkers programs that had been written by him for Pilot ACE. This program faced memory capacity issue of the system so Strachey recorded the program for a system in Manchester that had larger memory capacity. In 1951, as television technologies were being developed for an electronic company named Loral based in New York, an inventor named Ralph Baer suggested the idea of making use of patterns and lights for better works than for just calibrating equipments. Then he found that by offering the audience with capability to manipulate what projected on the TV sets, a change in role was seen to interactive manipulation from passive observing. This idea was taken to the supervisor that was squashed quickly as the company was already running behind the schedule time.
