Poker's popularity experienced an unprecedented spike at the beginning of the 21st century, largely because of the introduction of online poker and hole-card cameras, which turned the game into a spectator sport. Not only could viewers now follow the action and drama of the game on television, they could also play the game in the comfort of their own home. Broadcasts of poker tournaments such as the World Series of Poker and World Poker Tour brought in huge audiences for cable and satellite TV distributors. Because of the increased coverage of bet fair poker events, poker pros became celebrities, with poker fans all over the world entering into expensive tournaments for the chance to compete with them. Television coverage also added an important new dimension to the poker professional's game, as any given hand could now be aired later, revealing information not only to the other players at the table, but to anyone who cared to view the broadcast.
