My fiance pointed out something interesting when he was listening to WXTU recently. Their RDS display would occasionally display an ad for NTB (National Tire & Battery)... usually for a discount oil change. It would flip between that and the song info playing.
I caught a picture of it on WIP during one of the recent Eagles games... and have seen WOGL and AMP doing it as well.
Caught my attention the first time I saw it. Gotta give them credit for squeezing out every dollar they can.
