I believe it's a info. channel listing commercial sports programming available to commercial viewers only. It might be PPV, regular sports programming, or a combination of both. I read about this on another thread, actually.
It has been around for a while and just recently uncovered to residential subscribers...This is a PPV channel specifically aimed and and available to commercial establishements. There are some sports PPVs not available to residential subs that are available to commerscal subs.
