In a brief statement, Shell said Sunday would be his last day after what he called “an inappropriate relationship with a woman in the company.”
“I’m truly sorry I let my Comcast and NBCUniversal colleagues down, they are the most talented people in the business and the opportunity to work with them the last 19 years has been a privilege,” Shell said.
Shell has led NBCUniversal since 2020. He has been with the company since 2004.
Comcast made no mention of who will succeed Shell.
