The first computer games go back to the 50s when a nought and crosses game was created using an EDSAC computer. An effort at MIT ten years later led to a the multiplayer Spacewar game developed in a PDP-1. Even though these games were primitive, a game industry was born with the first games available in special locations – arcades. Today’s games are produced with modest Hollywood budgets and some are selling more than box-office hits. In this lecture we look at computer games and the gaming market. Also we cover the impact of gaming and the trends.
