Des Moines Register 09-16-07 Roses and Thistles: Shakedown at Cyclone Field A thistle to the ISU Athletics Department for charging Iowa fans $90 a pop for yesterday's intrastate game. Hawk fans had it better than Clones, who had to pony up a minimum of $125 for season tickets to get in. U of I folks were tuttutting about the stiff price, but this is just a business deal. That's something the Iowa Athletics Department knows all about. Ask the half-million cable subscribers who won't see U of I events because Mediacom is balking at the Big Ten Network's exorbitant demand for a cable-TV deal. Indeed, college sports is a profitable enterprise, which raises the question: How long can these schools justify their tax exemptions?
