Ad or Entertainment?
I watch almost no TV. In fact, the only reason I bought a TV in the first place is that my computer screen is too small to watch DVD's with other people. In my opinion, the average TV ad is better than the average TV show. Networks may be starting to catch on to this concept.
Meanwhile, here's an awesome ad in which an Audi drives through some of Escher's impossible mazes. (Link via Donald Sensing)
