Media giant Viacom has shaken things up among the executive ranks of its advertising sales unit, putting Jeff Lucas in charge of a consolidated group, The Wall Street Journal reports, citing people who are familiar with the situation.

“Mr. Lucas, who currently runs ad sales for Viacom’s group that includes channels like MTV and VH1, will add to his purview the Kids and Family Group, which includes the Nickelodeon fleet of channels,” WSJ reports. “Mr. Lucas will now have ad sales responsibility for Viacom’s entire portfolio of channels except for the BET unit, which will remain separate, the people say.”

The move comes amid a broader cost-cutting and restructuring effort for Viacom, the report notes. “Viacom last month pared down the company’s organizational structure from three groups to two, as MTV Networks Music & Logo Group President Van Toffler stepped down,” WSJ adds.

The company is dealing with recent ratings declines across much of its cable holdings.
