Hockey in reality show formats just don't work.
Do you remember that "Making the cut" reality show for the nhl?
...Didn't think so.
That was about as dreadful to me, as watching oil dry. "It's never going to end!!!" *Throws tv out of window*.
I don't think televising beer league matches would pickup much fan interest, either. I personally enjoyed it when they made roller hockey professional...but even *that* didn't get fans into a different form of hockey than what they're typically used to watching(Nhl, Junior...olympics).
I personally wouldn't bother tuning into beer league hockey myself.
