The participants include many of the world's best poker players. The championship was the first poker event to be televised on a major U.S. broadcast network and the first to be produced by a television network.Here you can watch World Heads-Up Championship poker videos The idea for the tournament was spawned from the success of the World Heads-Up Poker Championship[citation needed], held annually in at various locations in Europe, although only one World Heads-Up Champion ("Miami" John Cernuto) has competed in the National Heads-Up Poker Championship to date.
