Only one problem with your thinking. In order to get howard or cnn or fox a company needs money. Pandora is bleeding it every day with no end in sight. If you are counting on a buyout you should have bought SIRI anytime in the last 3-years and rode the Liberty wave. SIRI is a far better investment than P.
You don't think that GOOG, AAPL or FB have enough money? Keep in mind that AAPL already has deals with the music industry and they already know how many millions of iPhone users subscribe to Pandora. It would cost hundreds of millions of dollars for AAPL to create a similar personalized radio like Pandora and without guarantee. Pandora's model has already been proved successful with their subscribers, it now needs a company as powerful as AAPL or FB or GOOG to bring it to the top. Another thing is that SIRI depends on the life-span of their very expensive satellites and paid subscribers, Pandora does not.
I also think that Mel Karmazin will become Pandora's CEO when it gets bought out by AAPL, GOOG or FB. Then, when Howard Stern's contract with Sirius ends, you can bet that Mel and Howard will re-unite at Pandora. HS will have his own pay-per-listen/subscription channel al Pandora.
