> Small experiment: searching for "movie old man balloons" on Google and Bing.

Your experiment's results are not repeatable. When I do that here:

* Bing gives me 8 pages about Up (including that spoof site), one about Danny Deckchair, and a page about a magician who re-creates old movies with balloons.

* Google gives me 13 pages about Up (also including that spoof site), a book of best movie scenes on its page for The Third Man, and an article from The Rotarian from 1948.

Of course, some knowledge of how these things work teaches that this is a terrible methodology, given that it does not account for the fact that both Bing and Google tailor their search results to the searcher. One should at the very minimum log out of one's Google and Bing accounts, which you made no mention of doing.
