So what you are really asking is why did MMA fans become interested in the fights they want to see? Not that I think Glover/Jones is going to make more than Gus/Jones 2, but the point of your question doesn't make sense.
Right on the money. (pun intended)
Big money fights are good for the sport and can attract interest from people and media outlets that normally wouldn't care much.
