The Radio On The Bus Spews Out Ads, Spews Out Ads...

In yesterdays Wall Street Journal, it was reported that companies are vying for the rights to be the official radio station on school busses. In between ads for FrankenBerries and XBox360's there would preumably be some educational programming. The programming should act as a distraction to the stoned bus driver and the big kids picking on the little ones, but is it really necessary to blast a radio over a bunch of kids, or have school busses become quiter than their adult cousins while the kids are IM-ing to their seatmate via SMS?
