The exec, who had a key role in ushering in signature hits like Mad Men and Breaking Bad, was named COO in 2009. He has a five-year contract due to expire on December 31. His departure follows word last month that former CEO Josh Sapan was also stepping down after his own 26-year tenure. The company has installed former Showtime boss Matt Blank as interim CEO.
The Sapan-Blank news fueled speculation that after more than a decade as a publicly traded company, AMC Networks was perhaps taking a closer look at the vibrant M&a marketplace. The home of The Walking Dead has long been bruited about as a potential takeover target, but that decision rests with a small group of shareholders: the Dolan family, which controls the company.
