UFC events on Spike vs. pay-per-view

[whangarei]

Does anyone know the business tradeoffs for having UFC events on cable vs. PPV? I am curious because they showed UFC 75, with arguably their biggest fight ever, on Spike. So they obviously lost a lot of PPV revenue. Do they make this up by selling commercials, or do they just have events on cable occassionally to generate new fans and accept the decreased revenue for that event?
