Facebook has hired Antonio Lucio, HP's global chief of marketing and communications and a former Visa and PepsiCo executive, as its new chief marketing officer, according to a Facebook post by chief product officer Chris Cox. Facebook's previous CMO, Gary Briggs, left the company in January.

Why it matters: Facebook has had a rough couple of years fighting off a number of controversies, including fake news, election meddling, and improper use of its users' data, so it can surely use the help from a seasoned marketing exec.
