Commercials BEFORE the Superbowl

I thought this was awesome, because it's a collection of Superbowl ad teasers & contests, just like we were discussing in class yesterday. Most of these videos were released on YouTube, which is a sign that even organizations with enormous advertising budgets are seeing the potential reach and payoff of using a free medium like YouTube.

I think this is smart in a second way as well.  Since these companies are spending millions of dollars to advertise during the Superbowl, why not peak the audience's interest beforehand (for free) so that when your real commercial does come on screen, they stick around to watch?
