I was living in West Ham (within earshot of the ground) when they started all that business about trying to get a spot in the Olympic stadium – miles from anywhere, all the seats separated from the pitch by the width of the running track, but better for television. So I have generally assumed that the clubs are in it for the money first, and the fans only insofar as they’re needed to supply the money.
(In an economic sense, football entertainment is not a fungible good: most people who follow team A, whether they go to matches or just pay through the nose for the telly, won’t casually switch to following team B the way you might with washing powder, and as for following a different sport entirely that just doesn’t seem to happen.)
It’s all sportsball to me anyway; I don’t have that mental element of “supporting a team while not being directly involved” that most people seem to. The only sport I’ve found I enjoy watching is RallyCross, and that was something of a surprise; I got into it because JC Bouvier of Rallyman was posting videos to the HGG rules committee.
