Jeff Shell, C.E.O. of NBCUniversal, Steps Down After Inquiry

Jeff Shell, the chief executive of NBCUniversal, is leaving the company after an investigation into an inappropriate workplace relationship, the company’s owner, Comcast, said in a statement on Sunday.

In the statement, Mr. Shell said that today would be his last day and that he had had “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.”

Comcast’s terse statement did not say who would be replacing Mr. Shell at NBCUniversal, which he has led since 2020.
