David Letterman to step down. ‘Captain America’ will fly high.

After the coffee. Before getting my late night audition tape to CBS.

The Skinny: I hope CBS names a David Letterman successor in the next few months, I’m not sure I can take a year of speculation. As I say below, if this were 2004 instead of 2014 I’d say go get Howard Stern. Today’s roundup includes tons of coverage of Letterman’s big news as well as the box office preview and the latest on the Dodgers TV channel. Also, a review of HBO’s “Silicon Valley.”

Daily Dose: Fuse, the music channel owned by MSG, has been sold to NUVOtv, which is the Jennifer Lopez-backed network. While terms weren’t disclosed, speculation is that the deal is valued at north of $200 million. That is still less than the $300 million MSG was hoping it would get for Fuse. NUVO said it would not convert Fuse, which is available in more than 70 million homes, into an outlet for NUVO.

Farewell. David Letterman told his audience Thursday afternoon that he was ending his record run as a late night host in 2015. The move was not entirely unexpected as it was no secret that Letterman wanted to outlast Jay Leno, who stepped down from NBC’s “Tonight Show” earlier this year. Letterman has been a critical darling whose irreverent humor inspired a generation of comedians and established a presence for CBS in late night. Now the speculation will begin on who will replace him. Besides Craig Ferguson, who most feel is a long shot, gossip is starting about Jon Stewart and Stephen Colbert. If this were 10 years earlier, I’d tell CBS to go after Howard Stern. Of course, there’s always Jay Leno! More on Letterman’s legacy and who might succeed him from the Los Angeles Times, New York Times, Wall Street Journal, Variety, Hollywood Reporter, Deadline Hollywood, Vulture and Bloomberg.

Epic showdown. This weekend’s box office showdown is an American hero versus a biblical one as “Captain America: Winter Soldier” takes on “Noah.” Box office projectionists expect “Captain America” to win with a take in the $90 million neighborhood, which would be the biggest opening for a movie this year. Box office previews from the Los Angeles Times and Hollywood Reporter.

On the bubble. It’s that time of year when TV networks are busy making new shows in anticipation of the fall TV season. That means they are also making decisions on what current shows will live to see another season and which ones will be put out to pasture. USA Today and Vulture make their predictions on what writing staffs need to think about wrapping up and which ones should plan for next season.

Out at home? Time Warner Cable and DirecTV are so far apart on a distribution deal for the new Dodger channel SportsNet LA that they can’t even agree on whether they are negotiating. On Thursday, Time Warner Cable told the Los Angeles Times (that means me) that DirecTV had walked away from the negotiating table and indicated they would not carry SportsNet LA this season. DirecTV fired back that was not true and just another negotiating ploy by Time Warner Cable to try to pressure the satellite broadcaster into a bad deal. Meanwhile most fans in Los Angeles are still without the new channel, which is owned by the team but distributed by Time Warner Cable.

Inside the Los Angeles Times: Robert Lloyd on HBO’s “Silicon Valley.” Univision Radio is making cuts.
