iHeartMedia does more than radio they also previously owned a bunch of television stations and do billboard advertising. You may recognize their former name "ClearChannel" a little bit better. I would say this not only signals how difficult it is to make money from radio broadcast but how difficult it is to make money from any type of broadcast. They make use of a bunch of towers and satellites which I think is probably where the returns are failing in comparison to the internet. That whole industry needs to change anyways they are all living in a different age. This is what happens when the leadership of such a big corporation becomes so exclusive they fail to adapt and promote people with fresh ideas. They live an extremely narrow vision of reality- so now this vision is paying them all back the dividends that they earned.
