If you're interested in tracking the increasingly prevalent display of brands within movies, there's now a site that will make your job much easier. Interbrand's brandchannel.com has launched brandcameo, a compendium of product placements (paid or by chance) in movies. While appearing to have a very complete listing of placements, the site does not do a very thorough job, other than a few featured films, of explaining the placements. It simply lists them with minor, if any commentary.
