Taco Bell is looking to get into e-commerce as the Yum Brands chain reviews its digital business, Ad Age has learned.

The account has ping-ponged from DraftFCB to R/GA and back again in the course of a few years, and now the company is seeking a new shop for digital. DraftFCB will continue to handle broadcast, merchandising, multicultural and media for the fast feeder, which recently launched the tagline Live Mas. Taco Bell parent Yum Brands did not return requests for comment. SRI International is handing the review.
