What tournament is annually held in Las Vegas since the 1970s?
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.
AT&amp;T Byron Nelson The AT&T Byron Nelson is a golf tournament on the PGA Tour. It is hosted by the Salesmanship Club of 600-member civic organization, and has benefited the Club's nonprofit Momentous Institute since its inception. The tournament is held in May at the Four Seasons Resort and Club Dallas at Las Colinas in Irving, Texas, U.S. It is one of two PGA tournaments held in the Dallas-Fort Worth Metroplex – the only metropolitan area to host two PGA tournaments. The tournament is the leading fundraiser for charity on the PGA Tour and has raised more than $143 million. For much of its history, it was the only PGA Tour stop named after a professional golfer; it remains one of only two such events, along with the Arnold Palmer Invitational.
