Imo other leagues/competitions with just one huge final game (NFL, Champions league, Dancing with the Stars) make much more profit from this single event than stretching the series as long as possible could ever do.
The tension is much bigger, the date is much more important and one is rather inclined to take some time off to watch. I have watched the Superbowl more often than the NBA finals, just because it is less painful for me to do. (1 monday off). And I don't have a clue about football. The event is interesting though.
