Advertisers have learned from their mistakes over the past few years and are not posting their Super Bowl commercials -- at least not ALL of them -- online. Advertising experts say that companies found last year that they let the cat out of the bag too soon. They lost a lot of the excitement. The ad experts say if somebody sees the first two seconds of a commercial and says, “Oh I saw that last week on YouTube,” the other 28 seconds are meaningless. And that means a lot when you’re spending $4 million for each 30-second spot.
