If you watch football, you've seen the Coors commercials where they splice coaches press conferences with Coors fans asking irrelevant questions. These ads have inspired user generated copycats on YouTube that are just hilarious. The Coors ads are effective because they stand out and get people to wonder what they will come up with next, similar to what Apple has done with the PC vs Mac series. They have created content that viewers actually want to watch and have successfully embedded their product into this content.
