A GM spokeswoman confirmed that Mr. Halvorson has left the company. She said the automaker has not named a replacement.

What prompted Mr. Halvorson's departure is currently unclear. At GM, he was tasked with coming up with a "more accountable and innovative" media strategy, reporting into Megan Stooke, general director of global marketing services, according to Ad Age's story at the time of his hire.

Prior to joining the automotive giant, Mr. Halvorson had been global managing director for Publicis Groupe's Starcom Mediavest Group, where he oversaw the agency's global relationship with $35 billion global snacking company Mondelez International, GM said at the time.

Starcom was GM's media agency before the auto giant tapped Carat in 2012.

GM spent $1.66 billion on domestic measured media in 2014 and is ranked No. 3 on the Ad Age DataCenter's list of top ad and media spenders in the U.S.
