Interplanetary advertising
Some lunacy reported in New Scientist:
Nowhere is safe from advertising. [A potato-crisp manufacturer] is inviting the British public to come up with an advert for their nachos that will be broadcast into space from a radio telescope in Norway this June. The ad will be aimed toward the “habitable zone” around one of the stars in the constellation Ursa Major. This is 42 light years away, so peckish aliens might take a while to get here.
