NEW YORK (AP) — Super Bowl ads this year morphed into mini soap operas.

Dwayne "The Rock" Johnson shrugged off aliens so he could get more milk for his kids in a Super Bowl spot for the Milk Processor Education Program. Anheuser-Busch's commercial told the story of a Clydesdale colt growing up and returning to his owner for a heartfelt hug years later. And a Jeep ad portrayed the trials and triumphs of people waiting for the return of their family members.

The reason for all the drama off the field? With 30-second spots going for as much as $4 million and more than 111 million viewers expected to tune in, marketers are constantly looking for ways to make their ads stand out. And it's increasingly difficult to captivate viewers with short-form plots involving babies, celebrities, sex and humor — unless there's a compelling story attached.
