Doritos is running a make-an-ad-for-us contest in the UK. On June 12, 2008, one of the people-made ads for Doritos will be broadcast into the space from an ultra high frequency radar station in Norway. The ad "will be broadcast for 24 hours to a range of solar systems, some of which have planets that theoretically could support life." And be a potential Doritos market, apparently.
More details and hand-wringing (their space program is being cut) in the British press: "The transmission will be invisible to earthlings and is being directed at a solar system 42 light years away from Earth with planets that orbit its star '47 Ursae Majoris' (UMa). 47 UMa is located in the 'Ursa Major' Constellation, also known as the Great Bear or Plough."
Also: more space advertising.
