World Series of Poker
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. The format for the Main Event as a freeze-out Texas hold 'em game came the next year. The winner in 1970, Johnny Moss, was elected by his peers as the first "World Champion of Poker" and received a silver cup as a prize.
World Series of Poker
As of 2017, the WSOP consists of 74 events, with most major poker variants featured. However, in recent years, over half of the events have been variants of Texas hold 'em. Events traditionally take place during one day or over several consecutive days during the series in June and July. However, starting in 2008, the Main Event final table was delayed until November. The 2012 and 2016 Main Event final tables commenced in October because of the United States presidential election. As of May 2017, the World Series of Poker has done away with the November Nine concept and instead went back to the old format of crowning the Main Event winner in July.
