According to Friday's Wall Street Journal($), Atlanta trails only New York City, Los Angeles, and Washington, DC in terms of its contribution to ESPN's audience for Champions League games:
This stat truly surprised me, as I thought that a city with a heavy ethnic population like Chicago would out-strip Atlanta. And since we've been told by the national media for years that Atlanta is the worst sports city in recorded human history (although Michael Wilbon did carve out an exception for 14th century Florence, which was far too caught up in that Renaissance BS to go to games), I'm doubly shocked that Atlantans do anything sports-related.
On the other hand, maybe I have a Nielsen device and I've been single-handedly skewing the results. Gol TV, this might be a good time to renegotiate with your advertisers.
