In 1993, the year I began my career in video games, the public face of the industry was Mortal Kombat. In this martial-arts fighting game, two players would pummel each other until one opponent was sufficiently stunned—and then deliver a “Fatality” move. One character could grab his opponent's head and then rip his spinal cord out of his still standing body. Not surprisingly, parents, teachers and politicians were horrified. Congress held hearings about the game and its influence on youth. The episode led to the creation of the Entertainment Software Rating Board, which today rates games based on their age appropriateness.
