A+E Networks has appointed veteran investment banker David Granville-Smith (Digger) as exec VP and CFO.

Nancy Dubuc, A+E Networks president and CEO, announced Monday that Granville-Smith will succeed Gerard Gruosso, who is retiring after 30 years with the company.

Granville-Smith will now be responsible for leading all key financial functions across the company and providing strategic and operational thought leadership.

“Digger has spent over two decades advising media clients on some of the most groundbreaking and strategic maneuvers in the media business.  He is a true industry visionary with a wealth of experience,” Dubuc said in a statement. “I can’t think of a more seasoned executive for this critical role as A+E Networks writes its next chapter as a global media company.”

Granville-Smith previously served as a managing director and head of the media group in the investment banking division of J.P. Morgan. He has also provided strategic and financing advice to clients including A+E Networks, AMC Networks, Cablevision, CBS, Cox, Discovery, Disney, Liberty Interactive, Liberty Media, Madison Square Garden, Mediacom, MGM, News Corp, Sirius XM, Suddenlink, Time Warner, 21st Century Fox and Viacom.

In past years, he has worked on several strategic transactions including the split of News Corp into 21st Century Fox and News Corp, Cablevision’s sale of Bresnan Communications and the spin-off of AMC Networks from Cablevision.
