CBS Faces Late-Night Ratings Backlash After Stephen Colbert Exit Sends Viewers Toward Rivals

CBS may have expected a difficult transition after ending The Late Show with Stephen Colbert, but early ratings data suggests the network’s late-night gamble has created a much bigger problem than executives anticipated.

According to newly reported Nielsen figures, the first major night after Colbert’s final sign-off appeared to benefit CBS’s biggest rivals instead of the network itself. ABC’s Jimmy Kimmel Live! and NBC’s The Tonight Show Starring Jimmy Fallon both saw gains, while CBS’s replacement programming struggled to hold the audience that Colbert had spent years building.

For critics of the decision, the numbers are being viewed as a warning sign: CBS did not simply lose a host. It may have pushed millions of loyal late-night viewers into the arms of competitors.

The strongest early performance came from Jimmy Kimmel. On June 1, the first night that both Kimmel and Fallon returned with new episodes after Colbert’s departure, Kimmel reportedly drew 2.185 million total viewers in the competitive 11:35 p.m. time slot. That marked a 53 percent year-over-year increase. Even more striking, his audience in the key 18-to-49 demographic reportedly rose by 178 percent compared with the same night the previous year.

Fallon also benefited from the shake-up. The Tonight Show reportedly drew 1.301 million viewers that Monday night, up 10 percent from the previous year. His younger audience also showed growth, suggesting that viewers who once made Colbert part of their late-night routine may now be sampling other network options.

CBS, meanwhile, faced a much rougher picture. Comics Unleashed with Byron Allen, the program airing in Colbert’s former slot, reportedly drew only 628,000 total viewers on that same night. According to the report, that represented a 65 percent drop compared with the same time slot one year earlier, when Colbert was still on the air.

That contrast is what has made the backlash so intense. Colbert was not quietly fading away before his exit. His final episode reportedly attracted 6.74 million viewers, making it the most-watched weeknight episode of his 11-year run. Throughout his final season, The Late Show averaged around 2.7 million viewers — far above the early numbers now being reported for CBS’s replacement.

For longtime viewers, the result feels like a self-inflicted wound. CBS removed one of late-night television’s most recognizable figures, only to watch rival hosts gain momentum almost immediately afterward.

The decision has also become more controversial because of the broader political and corporate context surrounding Colbert’s exit. CBS announced the cancellation of the long-running Late Show franchise after months of scrutiny involving Paramount, Donald Trump, and controversy around a 60 Minutes interview with Kamala Harris. Colbert had publicly criticized Paramount’s handling of the matter, which made the timing of the cancellation even more sensitive.

CBS has framed the move as a business decision. But critics argue the ratings fallout makes that explanation harder to defend. If the goal was to stabilize late-night programming, the early data suggests the opposite may be happening.

Byron Allen has said he is not trying to replace Colbert or hold on to his audience. He has positioned Comics Unleashed as a different kind of comedy show with its own identity. But in the brutal world of network television, comparisons are unavoidable — especially when one show inherits the exact time slot of a late-night giant.

For CBS, the challenge now is not only about ratings. It is about trust, habit and audience loyalty. Late-night viewers often build long relationships with hosts. When a network abruptly removes someone like Stephen Colbert, many fans do not automatically transfer that loyalty to whatever airs next.

Instead, they change the channel.

And right now, that may be the biggest problem CBS is facing. The network did not just lose Colbert. It may have handed Jimmy Kimmel and Jimmy Fallon the easiest late-night advantage of their careers.
