The annual gladiatorial contest known as The Super Bowl is America's biggest sports event of the year, when more than 100 million viewers gather to watch the best professional football teams compete for the championship in the country's most popular sport.

Super Bowl Sunday is an unofficial American national holiday and ranks as the second-largest day for U.S. food consumption, after Thanksgiving. It's consistently the most watched U.S. television broadcast of the year.

And do those famously clever Super Bowl ads work? You bet they do. Companies that advertise in the Super Bowl often see a significant spike in sales, which can translate into stock gains.

This year, technology-intensive growth companies will figure prominently in Super Bowl ads, as they seek the attention of millennials who are increasingly concerned about their finances in a dicey economy.

For the first time, PayPal,  (PYPL - Get Report) SunTrust Banks (STI - Get Report)  and Intuit (INTU - Get Report) have all bought ads during the Super Bowl contest between the Carolina Panthers and Denver Broncos, which will air on CBS on Feb. 7. A 30-second spot costs a record $5 million.

If you're looking for "Super Bowl Plays," consider this trio of advertisers, which are all first-string stocks in their own right.
