PHILADELPHIA — Comcast has promoted Jennifer Khoury to chief communications officer, succeeding D’Arcy Rudnay who is retiring after 16 years in the role.

As CCO, Khoury will oversee external and internal corporate communications functions across the vast telecoms conglomerate, whose holdings include NBCUniversal. She has spent 21 years with Comcast, most recently serving as senior VP of corporate and digital communications, which includes leading comms for Comcast Cable.

“Jenn is a fantastic leader and the perfect person to lead us into the future. This well-deserved promotion will come as no surprise to those who know and have worked with Jenn. Her strategic vision and deep knowledge of the company and the industry has earned her the respect and support of our entire management team,” said chairman and CEO Brian Roberts.

Khoury will report to Roberts and senior executive VP Adam Miller, who is also an NBCUniversal executive VP. Rudnay will work through the end of the year as a senior advisor to Comcast’s executive leadership team.

“I can’t thank D’Arcy enough for her friendship and leadership, her unwavering commitment to our success, and her dedication and service to our company,” Roberts said.. “D’Arcy created our corporate brand and has led our communications strategy through some of the most important milestones in our history. We’ve been side-by-side through game-changing acquisitions, including NBCUniversal and Sky, industry-shaping technological innovations, and an incredible period of growth. D’Arcy has been a trusted partner to me for nearly two decades and her impact on our company cannot be overstated.”
