The World Series of Poker is the most prestigious set of poker tournaments in the world. The original World Series of Poker was started by Tom Morehead of the Riverside casino in Reno and was an invitational event. The set of tournaments the World Series of Poker (WSOP) would evolve to was the brainchild of Las Vegas legend, casino owner, and poker player Benny Binion as well as his two sons Jack and Ted. In 1970 the first WSOP at Binion's Horseshoe took place with seven players. The winner, Johnny Moss was elected by his peers as the first World Champion of Poker and received a silver cup as a prize.
