NEW YORK >> Jeff Shell, the chief executive of NBCUniversal, is departing the company after an investigation into inappropriate conduct, Comcast announced Sunday.

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, who had been with the company since 2004, was named CEO of NBCUniversal in January 2020. He oversaw the company’s news and entertainment networks, a premiere motion picture company, significant television and sports production operations and a leading television stations group, according to the company website. He also oversaw the company’s theme parks and a premium ad-supported streaming service.
