The further commercialization of space
JP Aerospace: $100 Space Ad
http://www.spaceref.com/news/viewpr.nl.html?pid=19428
"These "ads at the edge of the world" are on a platform carried aloft by high
altitude weather balloons. During the flight on board, cameras take pictures
of the ads with the blackness of space and the curvature of the Earth in the
background.
In the past, weather balloons have conjured up images of UFOs; now, images
of commerce are being created. After the balloons reach 100,000 feet, they
are released, and the platform descends to Earth by parachute."
