I think they are top 20 markets. Or close to it. There are not "30 sports markets" There is literally a market wherever there is a professional sports team. However there are 52 metered markets and 53 markets if you count Green Bay.
I am not "arguing just to argue" You aren't stating facts. That's all.
You wanna say "they aren't big markets " Fine. But don't spew nonsense afterwards.
Look it up if you want to. Or don't and keep making false generalizations because you don't reall know what you are talking about.
See which pro sports cities rank as the biggest TV markets, according to Nielsen. New York, Los Angeles and Chicago are the top three.
