Lots of folks seem excited about the first-ever embedded-code spot running on the Super Bowl. The 30-second spot will air in the fourth quarter, hyping Fox's 3-D animated film Rio through a tie-in with Rovio's uber-popular Angry Birds mobile game. The ad invites viewers to pause the action and seek out the code frame by frame to access a special level of the game and a chance to win a trip to Rio de Janeiro for the world premiere of the film on March 22. The Angry Birds Rio app debuts the same day. Sigh. I dunno, I just can't get into it. In fact, this entire post is bringing me down. Normally, I'd be cracking wise about the woeful Arizona Cardinals being the real angry birds of the NFL, or making some game-related joke about the Packers being the evil green pigs of SB XLV. Alas, I don't feel in the mood today. When you live in Boston and the Patriots aren't playing in the game, the Super Bowl is just not the same. How can you search for embedded code with bitter tears blinding your eyes?
