UPDATE: See the comments. ClearChannel says this was a paid ad. “The skull phone digital display was a paid advertisement that represented themselves as advertising for an art display. The claim that anyone allegedly “hacked into” the display through the internet or by entering the physical location is totally false.”
The plot thickens … I know the economy in Southern California isn’t humming along, but would it not cost a decent chunk of change to buy billboard time, particularly time on 10 boards in an A market???
A post on Wired’s blog suggested $7,000 or so – which I know my teenaged kids don’t have to blow on outdoor advertising.
All very strange.
From the SuperTouch blog, via MIT Advertising Lab.
Some guy, reportedly an 18-year-old, managed to hack his way into the PCs driving 10 LED boards operated by Clear Channel around L.A.
One of the images suggests he may have done so by climbing up to the billboard towers and plugging in directly, as opposed to getting at the players via an Internet connection.
