Roofarena: Selling Building Roofs in Manhattan

Roofarena isn't selling real rooftop ads of buildings in Manhattan, but rather using Google Maps with a layer that allows for the placement of images and links on rooftops, and then selling these ad spaces. After users purchase an ad space, they can set the image for the rooftop and add a website link to advertise. Roofarena also allows for free trials, though the rooftops you trial can easily be changed by others to their own. Roofarena is similar to the Million Dollar Homepage or The Big Word Project, all of which make money from advertisements through nearly疯狂 and unbelievable creative ideas. However, it seems that Roofarena has indeed successfully sold quite a few rooftop ad spaces, and it's unclear how much they will ultimately earn.
