Adding to the turmoil at Viacom, ad-sales chief Jeff Lucas is leaving the company.

Viacom named Sean Moran, a 21-year veteran of the company, as a replacement for Lucas, who was widely reported to be going to Snapchat once Viacom was done with the upfront.

Moran, who had been executive vice president of national brand sales, will report to Tom Dooley, Viacom's chief operating officer.

“Viacom has the industry's best sales organization, earning the highest regard from its partners by every measure — experience, innovation, creativity, and ability to deliver,” Dooley said. "Sean is the right leader to guide this group to new heights. He has been a standout performer with Viacom and his knowledge of our business and the advertising marketplace is unsurpassed."
