why does Pandora internet radio (the music genome project) have so many adds?

Question by Spenser: why does Pandora internet radio (the music genome project) have so many adds?
I know that Pandora’s music license is paid for by these ads, but a few years ago, there were just the adds on the side, not all those between songs and stations. What happened?

Best answer:

Answer by Common Sense
The music license fees have gone way up, and the more popular the service gets the more their bandwidth and server costs go up.
On top of that, it IS a business and they want to make a profit like any other business.
