Les Moonves, the head of CBS, has resigned from the media giant following allegations of sexual misconduct.
Accusations first appeared in the New Yorker, which have been investigated by CBS, and six new accusations emerged on Sunday.
The most recent accusations appeared in a new article in the New Yorker by Ronan Farrow. Farrow also wrote the article in July and received a Pulitzer Prize for detailing assault accusations against Harvey Weinstein.
Moonves said in a statement that he acknowledged three of the sexual encounters but said they were consensual.
“The appalling accusations in this article are untrue. What is true is that I had consensual relations with three of the women some 25 years ago before I came to CBS. And I have never used my position to hinder the advancement or careers of women. In my 40 years of work, I have never before heard of such disturbing accusations. I can only surmise they are surfacing now for the first time, decades later, as part of a concerted effort by others to destroy my name, my reputation, and my career. Anyone who knows me knows that the person described in this article is not me,” he said following the first accusations.
Moonves has taken CBS from strength to strength and it is the most-watched network in the US, making him one of the highest chief executives in the world.
Mr Moonves issued a statement on Sunday saying: “Untrue allegations from decades ago are now being made against me that are not consistent with who I am.”
Joseph Ianniello will serve as the president and acting CEO of CBS.
CBS has paid $20 million immediately in support of the #MeToo movement.
Shares in the group (NYSE: CBS) are down 3.73 percent at 53,98 (1715GMT).
