So much for AOL holding it together. According to Time Warner's new earnings report, "AOL reported the worst sales drop since ditching its subscription model last August," wrote MediaPost. Significantly, online ad sales -- which are now AOL's main source of revenue -- missed analyst expectations by as much as 10 percentage points.

AOL made some inroads in the mobile space recently, allowing users to check AOL mail, use AOL Instant Messenger, and more on the go. But after an initial flurry of activity, we haven't heard much since then. It's probably time to shore up defenses on that front, too.
