Clear Channel: Digital Billboards Rented, Not Hacked

The Los Angeles street artist known as Skullphone managed to get his iconic skull-holding-a-cellphone image to display on 10 prominent digital billboards throughout Los Angeles last week — leading some blogs to report that hed hacked into the signs. Alas, Clear Channel Outdoors, which owns the billboards, says no. "He paid to get it up," says spokeswoman Jennifer Gery. "It only ran for two days."

I was genuinely excited there could have been a vulnerability that would put such a powerful communications medium into the hands of smart and determined people. But it’s still pay to say in the land of free speech. +1 for the cynics.
