Can I call you Wettie since my pal GC gets away with that.
Wettie...you have the wrong suspect. My response in explaining the dependency on general fan interest was aimed at a poster who said it was completely irrelevant. Yes, you do need a sizable corporate base. You first need a sizable population that lives off/supports that sizable corporate base. Often, the greater the population the greater the likelihood you'll find a corporate base commensurate in size to that population. I've made the argument you're making several times in my many incarnations in places I choose to argue-- even using the critical mass term. So really, I know where you're coming from with that one.
Yet you cannot separate the two. The corporate base of any community will not buy into something - and keep buying - if there is no interest in the general community. In a sense, they are part of that same community.
What many of the posters here choose to ignore however, is the emotional side to this argument. The numbers as far as income, number of companies, population, arena size... blah, blah, blah... can all be present as well and yes, a sport can still fail. Amazing as that may sound to some of us number crunchers, it can happen. It isn't always poor management, where poor management is the mis-use of assets. I asked question earlier. Isn't there an emotional element to buying any nonessential good? What I describe above as a general interest from public and its corporate sector is also based on something psychological. That's the bigger nut to crack here in deciding who can succeed than simply adding up some numbers in the appropriate columns.
