Former Google and Motorola (Motorola was acquired by Google in 2012) executive Gary Briggs is joining the Facebook team as the social media company's first Chief Marketing Officer.

Briggs is officially replacing Eric Antonow, who served as Vice President of Product Marketing.

According to an article by Cotton Delo in Ad Age, "Mr. Antonow will stay on through the transition period and is leaving Facebook in September to work on a project related to his interest in education, according to a company spokesman. There will also be a change in the company's organizational structure. While Mr. Antonow reported to chief operating officer Sheryl Sandberg, Mr. Briggs will report to its VP-product Chris Cox."

It is largely anticipated that Briggs will be concentrating most of his activities, at least initially, on Facebook's mobile advertising and applications.
