The Super Bowl is all about the pig skin, glitz, glamour and, of course, the big money adverts.

This year the likes of Aerosmith's Steven Tyler will appear in a Skittles ad. Hyundai has gone all out with Hollywood heartthrob Ryan Reynolds, and Snickers has decided to put Willem Dafoe into a dress.

But getting your advert out to an audience possibly made up of more than 100 million people doesn't come cheap.

"It cost about $4.8 million (USD) and up to buy a 30-second spot in the Super Bowl," said Jeanine Poggi, a TV reporter for Ad age, "up from about $4.6 million last year and we see some advertisers like Anheuser-Busch for Budweiser and Bud Light buying multiple spots."

It won't just be big name celebs appearing in the adverts; cute animals will also appear. Heinz has a running pack of 'hot' dogs, while Honda has gone for a herd of singing sheep.

The Super Bowl and all the ads that surround out will take place on February 7th when the Carolina Panthers play the Denver Broncos in California.
