K1 will never become a mainstream sport if it remains exclusively on PPV. In fact I believe that PPV is what made boxing a "second hand" sport. Boxing used to rival baseball, football, and basketball in popularity. It used to regularly appear on TV, and while the major fights happened on PPV, anyone could watch top fighters without paying for it. However, this died out in late 80s (as NBC & ABC pulled out of the fight game) as fights became available only on cable or PPV. This decreased the audience for the sport. Even worse the PPV are expensive averaging $50 a pop, which is hard for everyone to manage. Personally I don't get all PPV events because I can't afford them. I usually wait for the replay a week later. However PPV events usually have 4-5 fights on them, where the replay only shows the main event. In cases where I'm interested in 2 or 3 of the fights on a PPV event (which is pretty often), if I can't afford to pay, then I lose out. Hopefully for K1 fans, the sport will eventually start appearing regularly on TV. Boxing at least has a fan base from when it was free, K1 doesn't even have that.
