"so far three friends have called me to tell me to watch this ad"
Perhaps they know you're the type to post on Slashdot and therefore think that you might be interested in Google's first-ever Super Bowl advertisement.
As for your other points, I think most people in this world have an inkling that Google has some kind of search service. In fact, it's the most popular search service in the world. Makes me wonder what the point of the ad is. "Gosh, I think I'm going to use Google to search on the internet from now on, instead of Alta Vista!"
