• CNBC anchors projected an air of mild panic about the news that Comcast would spin off the network.
• The media conglomerate announced it would create a new entity for most of its cable networks.
• Some NBCU insiders worry about the new entity's prospects and potential staff cuts.

CNBC anchors turned their signature irreverent style on themselves on Wednesday as their parent company, Comcast, became a headline in announcing plans to spin off the business-news network along with many other cable assets.

"We're going out into the cold, cruel world," Joe Kernan, a coanchor of "Squawk Box," quipped on air.

It's no secret that the cable business has long been in decline as viewers drift to streaming services. A fellow CNBC anchor, David Faber, came up with an analogy to describe the situation: "We've been on a life raft, and it's kind of been sinking. Now we're all going to be able to swim for ourselves, you know, so it's up to us."

"Maybe we can latch on to a bunch of other people drowning," Kernan replied.

Comcast brass presented the deal, in which it will spin off nearly all of its cable networks into a separate entity headed by Mark Lazarus, now the chairman of NBCUniversal's media group, as a way to grow its remaining businesses while enabling the spun-off networks to consolidate with others.

Bravo, the home of the "Real Housewives" franchises and other reality fare, will remain part of NBCU, along with its film and TV studios, the Universal theme park, the NBC broadcast network, and the streaming service Peacock.

"That Lazarus guy, he's amazing," Faber said, adding that he was "just trying to get on his good side."

Analysts — including those featured on CNBC — didn't hold back on Wednesday about what the spinoff means for the cable network.

"This is them saying we no longer want to be in this business, this is no longer a growth business," Rich Greenfield, a cofounder of LightShed Partners, said of Comcast during a CNBC segment. For CNBC specifically, he said, the question is "can these networks stand on their own?"

"Rich, I think I like you less today," Becky Quick, an anchor on "Squawk Box," responded later in the broadcast.

CNBC's Julia Boorstin laid out questions about the deal, suggesting the so-called SpinCo could make meaningful acquisitions from other media companies in transition, like Warner Bros. Discovery, Paramount, and Starz.

"One of my sources very close to the situation said, 'This isn't the end, this is the beginning,'" she said. "The question is what else does this company acquire, how do they try to squeeze as much revenue as possible from these linear networks, and what do they do with them from a digital perspective in terms of streaming. And what do they do in terms of non-television revenues, things like events, things like communities."

Elsewhere, others inside NBCU had their own questions and concerns about the spinoff.

One question for CNBC folks is whether they'll maintain the prestige and workplace benefits that came with being part of Comcast. There's also a question of what separating MSNBC could mean for NBC News and local NBC stations. MSNBC's left-leaning tilt has sometimes complicated things for straight news-focused NBC News and local NBC stations.

Anxiety was running high among some staffers at CNBC in London, who worried that international offices could be hit first by any cuts in shows or personnel resulting from a spinoff. These people, like some others in the story, spoke on the condition of anonymity for fear of workplace repercussions. Their identities are known to Business Insider.

One concern is that the spinoff could make it harder for NBCU's separate but co-owned news outlets to compete. NBC and CNBC have closely collaborated on reporting about topics like Elon Musk's role in the Trump administration that draws from CNBC's business expertise. NBC also relies on CNBC's sports coverage.

An NBC News staffer told BI that some in the newsroom felt "blindsided" by the news.

"The message has been to integrate as much as possible, so I definitely think this raises a lot of questions about whether that can continue," this person said.
