Did you know the first publicly demonstrated electronic game was created in 1950? Bertie the Brain was an arcade game of tic-tac-toe. Bertie was notoriously hard to beat. In the game, human challengers made moves using an illuminated keypad and Bertie immediately countered on the game board, invariably winning.
