The last I heard, pool on ESPN works like this:
You organize an event. You pay a production crew to film it. I guess you round up the commentators and take care of them. That will cost you tens of thousands to produce a tape.
You take the two-hour (with commercial slots) tape to ESPN, and say, "Please, sir, is this good enough for you to show?"
And then they say, "It's OK. You get part of the commercials in the first two times we air it, and then the tape is ours to use as we see fit."
That may have changed, but ESPN was absolutely uninterested in investing their time and money to produce a standard pool event.
