The Wall Street Journal said the resignation of MTV Networks President Michael Wolf and Nicole Browning, a marketing exec at the company, comes four months after a key change in Viacom's top executive position.
Ever since Viacom Chief Executive Officer Philippe Dauman took over the post after the forced departure of his predecessor, Tom Freston, the executive has made it his mission to revitalize MTV Networks.
While the decision to force Wolf out had been predicted for the last few months, the company's move against Browning, who has worked at MTV for 20 years, was a surprising decision.
Browning will leave her post immediately, while Wolf will remain with the company until February.
The Journal said that Peter Low, another top official within Browning's division, also will leave the company.
