Hey, remember the convo the other day about radio ratings? I have news on that front :-) They used to calculate ratings by using a diary system, which is deeply flawed at best. Now they've been using a Personal People Meter that works kind of like a Neilson box. If you change the station, it logs that, along with what station you changed to and how long you listened. It's much more acurate!
