@WS - you are charmingly naive :)
It's product placement. I bet you $100.00 to the charity of your choice.
(It'll be listed in the credits ... not sure I can face it a second time - good movie, but I preferred the last series, with Tobey Maguire and Kirsten Dunst)
CLUE 1: Yes, a few movies featured Google - but then they tended to feature anonymous searches (looking for a sponsor, no-one buying?) .... now it's pure (and very obviously) bing.
CLUE 2: There's very, very, very few brands in movies that are NOT 'placed'
And BTW - unless it the movie is set in a particular period, they'll go to the highest bidder. Hollywood ain't a charity, or a fanboi. It's a business. Nuff said.
