tanner said:Charlottle includes areas that are geographically further away than the mentioned counties around Orlando. Orlando should be the #24 market not Charlotte.
Radio markets are defined by a strictly applied criteria based on the amount of listening to stations "home to the metro" and commuting from each county into the central area of a metro.
When markets are surrounded by other metros, as Orlando is by the Tampa / St. Pete, Lakeland, Gainesville markets, it can not be any larger and its stations don't get that much listening, anyway.
Radio MSA's are not always the same as Census MSA's. One means Metro Survey Area, the other means Metropolitan Statistical Area and the criteria for inclusion of areas is different.
