Early electronic games were primitive and annoying, but in 1978 Milton Bradley changed all that with Simon. The game of memory and reflexes developed by Ralph Baer and Howard Morrison was a massive smash hit, with just four buttons and some blinking lights. Milton Bradley launched the game at a glitz event at New York's disco den Studio 54, and that holiday season it was the must-buy toy for American kids. Parents were frantic to get ahold of one, and fistfights broke out in stores.
