They would have to be enormous to be seen from earth. When viewed from earth the moon only has a visual size of approximately 1 cm so the ad would have to be a thousand of kilometres across to just appear miniature from our perspective.

    What if they use giant projectors directed a earth, you would see the ads on the clouds, in the sky! Wouldn't that be awesome?

    That's not how light works. In order to be bright enough to illuminate clouds on earth it would have to be brighter than the sun at its source point because of the Inverse-square law

    The techbros already have this idea with a satellite it wouldn't work with that either for exactly the same reasons and the satellite would have been way closer.
