CBS and AOL have recently inked a deal to offer a large number of radio streams online. As part of the agreement, CBS, the second-largest radio broadcaster in the U.S., will offer streams of its radio shows free of charge using AOL's online network.

CBS intends this move to aid expansion of its online presence and get them a foothold in the streaming radio market, which they also hope to monetize through advertising. AOL, in the other hand, gains a large chunk of exclusive content to offer their users. Sounds like a win-win situation for the companies, but for the smaller startups it may reduce their chance of success.
