It's Super Bowl Sunday, and the San Francisco 49ers and Kansas City Chiefs are locked in a battle to see who will be crowned champions of the 2019 NFL season. But those teams aren't the only ones with plenty on the line during the biggest event of the year. It's also a massive competitive arena for the world of advertising. Because of the game's massive annual viewership, it's also one of the top marketing opportunities for different brands. Every year, companies try to one-up each other with the use of celebrities, humor, talking animals, talking babies, and other bizarre strategies to get the public buzzing. 

In recent years, it has become customary for companies to release their Super Bowl ads online prior to their actual airing during the game. Some may argue that this leads to anti-climactic viewing of the commercials and spoils the mystique, but there's still plenty of interest (and money) in advertising during the big game. 

Here you can find some of the ads airing during Super Bowl LIV between the 49ers and Chiefs on Sunday.
