In case you can't wait until Sunday to see the Super Bowl ads, here are a few teasers. At an average of $3.5 million for a 30-second spot, companies need to get their money's worth, so we're seeing some pre-game, viral promotion.

According to Reuters, the Super Bowl is one of the few TV shows that still garner large audiences: about 100 million people are expected to watch the game on February 5. And yet companies will supplement views by promoting their ads on social media sites. Coca-Cola's commercial, for example, features computer-generated polar bears who will have their own Facebook page and Twitter hashtag (#GameDayPolarBears). Not to be outdone, Pepsi is encouraging fans to watch Melanie Amaro perform "Respect" and then download a video using the Shazam app.

As always, the Super Bowl ads, like this one from Priceline, target their audience.

Discussion Starters:

• How successful do you think these companies' social media strategy will be? Will it achieve their objective of expanding viewers and air time?
• Watch a few of the Super Bowl ad previews. What techniques do they use to target game watchers?
