that has created false ratings due to drive by listening. If a PPM panel member was sitting in a little diner with a radio playing behind the counter, that station would get credit for his ears...even if the panelist never paid attention to the content.
There are far fewer instances today where one would be likely to find a radio playing in a business, thanks to ASCAP, BMI, and SESAC looking to collect royalties for such. What is far more likely to be heard in public settings is sports play by play, that's one of the reasons (besides some contracts being up this year) there was a lot of jockeying and shuffling of game rights a couple of months back.
