Amazon’s Project Kuiper, with its plan to put thousands of satellites into low-earth orbit to provide internet access to people who don’t have it, reminds me of the scheme by the Bob and Ray Laboratories to build the Bob and Ray Orbiting Satellite and sell advertising space on it. To those who asked whether a satellite might be too far away for the billboards on it to be readable, Bob and Ray replied that they planned for it to orbit 28 feet above the earth’s surface.
