I don't know how much it costs to buy a 30 second spot on the MTV Music Awards, but I bet it was more than John Lanier paid for the ad to the right.
I took this screen shot from an ad that appeared about halfway through the program. If you know the answer to that question, just text it in! I had to hit the replay button on my TIVO to discover that doing so would cost 99 cents since it was a "subscription service." (That disclaimer was on the screen for just five seconds.) MTV should be ashamed for allowing it.
