Half a million dollar buy in on high stakes poker
I don't know why they did that but it's a pretty good bet that Doyle Brunson is the reason, not anything thought up by the producers. If there's one thing Doyle has shown himself to be good at over the years it's being able to build an ultra-high stakes poker game. He knows the players he wants in the game and he knows how to structure the game to attract those players.
I don't think the changes are about television. I think they're about Doyle.
