when was the first video game released to the public
Early history of video games The earliest known[citation needed] publicly demonstrated electronic game was created in 1950. Bertie the Brain was an arcade game of tic-tac-toe, built by Josef Kates for the 1950 Canadian National Exhibition.[10] To showcase his new miniature vacuum tube, the additron tube, he designed a specialized computer to use it, which he built with the assistance of engineers from Rogers Majestic. The large metal computer, which was four meters tall, could only play tic-tac-toe on a lightbulb-backed display, and was installed in the Engineering Building at the Canadian National Exhibition from August 25 to September 9, 1950.[11][12] The game was a success at the two-week exhibition, with attendees lining up to play it as Kates adjusted the difficulty up and down for players. After the exhibition, Bertie was dismantled, and "largely forgotten" as a novelty. Kates has said that he was working on so many projects at the same time that he had no energy to spare for preserving it, despite its significance.[11]
