A look at the Super Bowl ads that have been released so far...

New York — Advertisers including Budweiser, M&Ms, Groupon and others have begun to release their ads ahead of Super Bowl Sunday to try to drum up some buzz.

It's a crucial time to capture attention since marketers spend $5m per 30-second spot for airtime alone.

While teaser ads abound, we take a look at the full Super Bowl ads that have been released as of Monday. So far advertisers are mostly focusing on silly humour and heartwarming messages.

SEE THE SUPER BOWL ADS RELEASED SO FAR:

Budweiser: The beer maker's ad features a brewery that turns out cans of water for places in need, to the tune of Stand By Me.

Febreze: The air freshener goes all in for toilet humour with a pseudo-documentary ad about Dave, a man whose "bleep don't stink." The kicker is that David is not at your Super Bowl party — so you should use Febreze.

Groupon: The deal-site's ad features Tiffany Haddish and shows football players kicking a football at a rich man who doesn't support local business.

Lexus: The carmaker promotes its new luxury sedan with an action-packed ad featuring the Black Panther character from Marvel's new movie.

M&Ms: The chocolate candy's ad shows a cartoon M&M character transforming into Danny DeVito after he finds a lucky penny and is relieved that no one wants to eat him.

Pringles: Bill Hader stars in the snacks' ad that introduces the made-up practice of "flavour-stacking," or eating different flavours of Pringles together to create new flavours.

Michelob Ultra: The commercial, dubbed The Perfect Fit, enlists Chris Pratt to illustrate how to balance a healthy lifestyle with beer-fuelled fun.

Doritos Blaze Vs Mountain Dew Ice: Pepsi Co, has brought two of their brands together in an epic battle between Game of Thrones' Peter Dinklage and Morgan Freeman.

The Super Bowl between the New England Patriots and Philadelphia Eagles airs on Sunday night on NBC.
