ST. LOUIS - The Super Bowl is Sunday and millions of people are looking forward to the game. The commercials before, during and after the game have become 'must see TV.'

Some advertisers have released their Super Bowl ads ahead of the game. Many of them are posted on YouTube.

This year, 30 seconds of airtime costs upwards of an estimated $4 million.

You'll get to see what other advertisers have to offer on February 3 when the San Francisco 49ers take on the Baltimore Ravens for Super Bowl 47 in New Orleans.
