Reply #55: It's not necessarily ABC News

[LTR]

ABC also has a network that syndicates national advertising spots, and I get the feeling that's where this list comes from (yes, it is legit - ABC has even admitted it). Radio stations with all kinds of formats subscribe to this service. I'm more familiar with Westwood One's similar service, and not as familiar with ABC's, but I assume there's really little difference.

Clients with these advertising networks do have a choice of what formats or programming they can advertise on. I worked at a radio station cluster a while back, and there were certain sponsors that were off-limits to our given formats (one was a rock station, the other was country). Most were okay for both, some picked one over the other, and some were off-limits to both.

I assume Premiere (Clear Channel) has a similar service for their stations.
