While sponsors may not specifically tell stations what to do, creating programming to garner listeners to attract advertisers is recognizing client needs and wishes, e.g. few 60s songs on classic hits stations because advertisers don't want that demo.
But say your biggest advertiser, a big car dealer for example, calls up and says they don't like a particular song and threaten to pull their ads if you don't take it off, how altruistic might most stations be?
When WHK was attempting to renew the Browns contract, Art Modell told them he didn't like the kind of audience their country format attracted, so poof...they suddenly became rock and roll oldies. There were other reasons and Modell bought WWWE and moved the team there anyway (He was good at moving things, wasn't he?) the point is advertisers have power, both subtle and covert.
