"Others including Caesars and Harrahs claimed this was irresponsible gambling and sent out the wrong message."
May be true. Some casinos promote 'responsible gaming' more than others. Dont our casinos do that? Oh, yes, I just remembered, they wait until you lose your shirt before doing anything

The whole thing was a good PR stunt in my opinion. Someone like Max Clifford or Saatchi must have been involved.

"live broadcast of gaming as i understand prohibited if it could be used to bet elsewhere"
This came up once before over here. Something about 'secondary betting' (ie betting on the outcome of someone elses bet) being prohibited.
I remember before the days of the big chains, you could get a bookie to take a bet on anything.
