Delete Billboards

Pleaseenjoy
Billboards are an eyesore. And until now, I figured they were okay in cities as the landscape is already kind of messed up but New Yorkers are tired of over-billboarding. Plus, lots of them are illegal so people are making money off of illegal eyesores. Great.
On April 25th, 2009, Jordan Seiler and PublicAdCampaign.com organized a massive takeover of these billboards called NYSAT. I really think it's about time. Hasn't advertising moved beyond billboards yet? Does anyone look at them? Do they work anymore?
