PokerStars is the largest online poker cardroom in the world. 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. PokerStars is the headline sponsor and part owner of the European Poker Tour (EPT), Asia Pacific Poker Tour (APPT), Latin American Poker Tour (LAPT), Australia New Zealand Poker Tour (ANZPT), Italian Poker Tour (IPT) and Czech-Slovak Poker Tour (CSPT). PokerStars sponsored an event on the World Poker Tour called the PokerStars Caribbean Adventure (PCA). 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". PokerStars offers a downloadable poker client for both Windows and Macintosh operating systems, offering the same features to users of each client.
