The idea of a World Series of Poker began in 1969 with an event called the Texas Gambling Reunion. It was an invitational event sponsored by Tom Moore of San Antonio, Texas, and held at the Holiday Hotel and Casino in Reno.
This inaugural event was won by Crandell Addington. The set of tournaments that the World Series of Poker (WSOP) would evolve into was the brainchild of Las Vegas casino owner and poker player Benny Binion.
In 1970, the first WSOP at Binion’s Horseshoe took place as a series of cash games that included five-card stud, deuce to seven low-ball draw, razz, seven-card stud, and Texas hold ’em.
