Since then, branded content has expanded to follow viewers wherever they are - in video games, movies, television shows, web-based videos, tutorials and more.
The Uncle Drew journey from YouTube to advertising campaign to full-length feature film began in 2012 when NBA star Kyrie Irving first took on the role as the basketball-playing septuagenarian Uncle Drew. The first video, written and directed by Irving, attracted over 50 million views on Pepsi's YouTube channel. A number of sequels followed, adding to the roster basketball pros such as Kevin Love, Nate Robinson, Maya Moore, Baron Davis and Ray Allen.
Uncle Drew's embodiment of all things street ball, such as good-humoured trash-talking and performative one-upmanship, adds an authenticity that a traditional advertisement wouldn't be able to provide, said Jay Tucker, executive director of the UCLA Anderson Centre.
The film cost studio Lionsgate less than US$20 million ($29m) to produce before marketing, according to the Hollywood Reporter.
Compare the money it cost to produce Uncle Drew to the US$5m Pepsi paid for a 30-second Super Bowl ad this year, Einstein said.
