Legendary broadcaster Bob Costas looking to leave NBC?

Bob Costas’ days at NBC could be numbered. Here’s why.

Bob Costas has been a part of NBC for more than a generation. That relationship could soon be ending.

According to Andrew Marchand of the New York Post, Costas and NBC are in talks to part ways.

In the history of sportscasting, no broadcaster has probably been more associated with one network than Bob Costas and NBC.

Now, after nearly four decades in which Costas has been the lead announcer on Olympics, World Series, Super Bowls and late-night talk shows, Costas and NBC are in discussions to end the relationship, sources have told The Post.

If a deal can be struck, it would mean finishing Costas’ current multi-million contract three years early as it is goes through 2021, according to a source. The contract calls for exclusivity for NBC, besides the work Costas does for MLB Network.

Part of the reason? Costas no longer is invested in NFL coverage, and wants to do something that sounds like a talk show.

Costas wants to pursue a journalism show that would feature interviews, commentaries and a critical look at the world of sports and perhaps other topics. NBC rarely utilizes Costas on-air after he stepped away from his last major roles on the Olympics and the NFL.

“Sometimes you get to a point where it is not a fit anymore,” Costas said. “It doesn’t mean that anyone is angry or upset.”

If Costas steps away, Mike Tirico–who recently jumped to NBC from ESPN–is a possibility to become the new face of sports at the network.
