Pandora's stock has had a fantastic year, to say the least. Until the launch of iOS 7 and iTunes Radio, Pandora just about tripled its value since the start of 2013. But since the start of the week, it's down over 5% after it said its growth is slowing and with news of iTunes Radio's early success.
Meanwhile, Pandora's outer space rival, Sirius XM, also took a hit this week. The satellite radio company lost more than 2% since opening on Monday. Like Pandora, this year was being very good for Sirius XM; its stock had been up 37% from January until iTunes Radio's launch.
Sirius XM's market cap is $23.8 billion while Pandora's is $4.5 billion. Their combined total of $28.3 billion is just two-thirds of the cash Apple is sitting on. The two streaming companies' combined annual revenue of $4.1 billion is about what Apple makes in less than nine days. Financially speaking, everything these two companies have is the equivalent of what Apple finds in its sofa cushions.
So, will iTunes Radio put an end to the likes of Pandora and Sirius XM?
