The 2018-19 broadcast season got off to an unexpectedly turbulent start last fall when a whopping three network chief jobs turned over in the space of just two months. In September, George Cheeks and Paul Telegdy jointly stepped in as NBC Entertainment co-chairmen, replacing the departing Robert Greenblatt. A month later, Charlie Collier was named Fox Entertainment CEO in October, taking over for Fox Television Group chairmen and CEOs Dana Walden, who will be moving to Disney when the Disney-Fox deal closes, and Gary Newman, who will be leaving the company. Then Karey Burke took over as ABC Entertainment president in November, when Channing Dungey departed (she quickly landed at Netflix). While all four execs focused on getting up to speed during their first months in their new roles, they’re finally ready to open up about their respective priorities for their networks, their message to advertisers and why they still believe in broadcast TV.
