World Series of Poker
The World Series of Poker (WSOP) is a series of poker tournaments held annually in Las Vegas and, since 2005, sponsored by Caesars Entertainment Corporation (known as Harrah's Entertainment until 2010). It dates its origins to 1970, when Benny Binion invited seven of the best-known poker players to the Horseshoe Casino for a single tournament, with a set start and stop time, and a winner determined by a secret ballot of the seven players.

Prior to 1979, the only high dollar tournament a person could enter was the WSOP. 1972 WSOP Main Event Champion and outspoken ambassador for poker Amarillo Slim saw this as an opportunity. "The World Series of Poker was so successful that everybody wanted more than one tournament," he said. Slim called upon his connections and friendships with poker's elite to start a new tournament in the February 1979. Before the SBOP had developed a reputation of its own, many of the most respected names in poker attended the tournament "more to support Slim and take advantage of the very fat cash games the event would obviously inspire." Slim modeled his SBOP after the WSOP with several events and a $10,000 Texas Hold'em Main Event.
