NEW YORK CITY — CBS News is shutting down its radio service after nearly 100 years, with the service ending on May 22. Editor-in-chief Bari Weiss and president Tom Cibrowski announced the shutdown on Friday.

More than 700 affiliate stations will be affected by the radio service shutdown. The shutdown-related cuts could impact about 6% of CBS News's workforce, or more than 60 people. Employees will be notified by the end of the day if their job has been affected by the shutdown.

Weiss and Cibrowski said that a "shift in radio station programming strategies" and economic challenges "made it impossible to continue the service." They said, "While this was a necessary decision, it was not an easy one."

CBS News is planning to lay off dozens of employees across the company as part of broader changes. Weiss and Cibrowski said, "Parts of our newsroom must get smaller to make room for the things we must build to remain competitive."

Weiss and Cibrowski said, "It was no secret the news business is changing, and we need to change along with it." They also said, "New audiences are burgeoning in new places, and we are pressing forward with ambitious plans to grow and invest so that we can be there for them."

David Ellison took control of CBS News after he took over Paramount as part of a merger with his Hollywood studio Skydance last year. Ellison hired Bari Weiss, a former opinion writer, as the editor-in-chief of CBS News in October of last year.

Weiss has criticized broadcast media for being too partisan and liberal and aims to change editorial decision-making at CBS News. She founded the news site The Free Press. Weiss said, "CBS needs to shift away from undifferentiated 'commodity news' toward exclusive reports that people can't get anywhere else."

Weiss said, "If you can get what we're selling in five other places, in 10 other places, in 100 other places — that's probably not a thing we need to double down on." She also said, "Our strategy until now has been to cling to the audience that remains on broadcast television. I'm here to tell you that if we stick to that strategy, we're toast."

In December, Weiss decided to pull a segment about the Trump administration's deportations of Venezuelan men to a detention center in El Salvador. The decision prompted backlash inside and outside CBS News. In January, Weiss unveiled plans to hire new contributors and restructure CBS News's digital news coverage, bringing on over a dozen new contributors.
