The logo of a street artist in LA named Skullphone started popping up on digital billboards around the city owned by Clear Channel. Awesome! said the collective street art world. The kid has hacked into the big media monster Clear Channel's network! It's digital graffiti! It's culture jamming! It's the new media revolution! But then it came out that Skullphone had just bought time on the billboards, like every other schmoe. Is that even cool? I'm sure Michel Foucault would have something deep to say about this, but I'm not sure what it would be. Money ad street art! [Wired]
