PokerStars is the largest online poker cardroom in the world. It has held this title since 2007.
PokerStars' satellite tournaments produced the 2003 World Series of Poker champion, Chris Moneymaker, as well as the 2004 champion, Greg "Fossilman" Raymer. Those two now act as spokespeople for the cardroom, as does 2005 World Series of Poker champion Joe Hachem, also a regular player on the site. In March 2007, poker room manager Lee Jones announced his retirement, effective April 1. His successor has yet to be named.
Launched in September 2001, PokerStars was once owned by a Costa Rican company, Rational Enterprises. With its company headquarters on the Isle of Man in the Irish Sea. Later, this company was sold to Amaya Gaming, under the direction of billionaire David Baazov, who later resigned in disgrace.
PokerStars overtook PartyPoker as the world's largest online poker room at around the time the U.S. Congress passed the Unlawful Internet Gambling Enforcement Act. Many sites, including PartyPoker, immediately suspended business with U.S. gamblers, while others, including PokerStars, did not. On May 19, 2007, PokerStars dealt their 10,000,000,000th hand.
PokerStars is the headline sponsor of the European Poker Tour. PokerStars sponsored an event on the World Poker Tour called the PokerStars Caribbean Poker Adventure. The World Poker Tour no longer stages this event, so it is now a stop on the European Poker Tour. In 2005, eGaming Review named PokerStars.com the "Best Poker Operator of the Year".
