Help needed

John Spinda at Kent State needs help finding some sports media information. Here's his request and contact information; if you can assist contact him directly or post the information here--

I am having some difficultly locating figures and percentages of sports fans nationally. I have found some market research that has suggested about 90% of Americans consider themselves "fans" of sports, but it is really vague and outdated. Is there some publication or outlet that regularly publishes this kind of data (yearly, etc.). Or is there any ideas about where I'd find this data. Basically, I am looking for some up-to-date, reliable figures on the popularity of professional and/or college sports in our society to help make some arguments in my dissertation.
