A recent issue of The New Yorker included an advertisement by the Discovery Channel about their "Greatest American" contest and TV series. Beginning June 5th and hosted by Matt Lauer, I'm guessing it will be a biography-type show. A long list of great Americans is in the running. This particular ad was interesting in that it listed two of the nominees: Bill Gates and Walt Disney... who both "Changed the world with a mouse."
