I wonder if FLY92 was caught using the numbers for selling? But that usually gets the whole market embargoed i.e., 12+ ratings completely unavailable to the trades.
The Arbitron ratings (including the latest trends) are loaded with stations that aren't Arbitron customers. If Cumulus, and now maybe CC, carry through on their threats to stop subscribing in markets 101+, their stations in those markets will not disappear from the publically-available ratings. But Arbitron might stop doing ratings entirely in some of the markets if they become unprofitable.
