I have always wondered if advertisers could focus their message on a particular station to get their message across or if they have to buy the entire cluster such as iHeartRadio or Audacy?

If I'm a car dealer, I'm looking to buy time on all of the stations within a corporate tent.

This is a family message board, so I'll try to edit myself for the sake of this discussion.

If I were to advertise beer, motorcycles, men's prophylactics, etc., I would be looking to focus my ads on stations such as The Drive/97.1 and Rock 95.5 to name two. I probably wouldn't be looking at WLIT-FM and chances are, they may not accept even a tasteful ad. They're a ratings powerhouse, however, I'm trying to reach a particular demographic.

To sum it up, do advertisers have the option to buy time on one station or is it the entire bundle within the cluster?

Finally, would a sales department recommend advertising during certain hours on a given station if the cluster was the only option?

As always, thank you for your time.
