You won’t find a billboard in space… yet.

But astronomer James Lowenthal told Gizmodo that while there used to be only a handful of mostly government agencies involved in spaceflight, there are now “hundreds or thousands of private space companies vying for a piece of the space pie,” some of which may be interested in clogging up the night sky with ads.
That may be a lucrative endeavor: A 2022 study estimated that while a constellation of ~50 satellites would cost $65m, it could generate ~$111m in profit across three months and 24 ad configurations.
