One game every 3 or 4 months? That would mean there was only one (possibly two) televised games the entire season.
They do have a deal with ESPN2 and ABC to have games televised every week, and ESPN/ABC go out of their way to hype this... I see TONS of commercials about it while trying to watch the channels.

That's this season's TV schedule... Not as many TV games as the NBA, but also not as many teams, and not enough interest.
