Background
Stephen Colbert closed out his tenure on The Late Show with a final episode that delivered a rare ratings spike for network late night television. According to reporting by mmwachiro for Adweek, Nielsen’s preliminary live fast national ratings put the programme at an average of 6.74 million total viewers for Thursday night. The episode featured celebrity cameos, musical numbers and a surprise appearance by Paul McCartney, who closed the show with an in-studio performance of The Beatles song Hello Goodbye.

Ratings and context
That 6.74 million figure makes Colbert’s finale the most-watched weeknight episode in the show’s nearly 11-year run. It also nudged past his own series premiere, which drew roughly 6.55 million viewers on September 8, 2015, though it remains far short of the show’s single biggest audience: a post-Super Bowl broadcast that reached about 20.55 million viewers in February 2016. For longer-term perspective, Nielsen’s live+7 data show The Late Show averaging 2.69 million viewers in the first quarter of this year, a number that illustrates how unusual the finale’s audience was compared with the programme’s recent week-to-week pull. https://www.nielsen.com/
Why the finale performed
Television in 2026 is an atomised marketplace. Streaming, social short-form video and time-shifted viewing have eaten away at appointment television. That makes last-night spikes like Colbert’s both rare and commercially useful. Finales with clear narrative or cultural hooks, high-profile musical guests and star-studded cameos can still concentrate attention in a way ordinary episodes struggle to match. The presence of Paul McCartney and the tone of celebration amplified the event quality and ensured extensive social-media chatter, which in turn drives linear viewing for audiences inclined to watch live.
What the numbers tell advertisers and networks
A near-7 million audience for a late night send-off is valuable beyond prestige. For advertisers and CBS, it is an opportunity to convert fleeting goodwill into premium ad dollars, product tie-ins and licence deals. Yet it is equally important not to overread the result. Event-driven viewership is inherently lumpy. Nielsen’s live fast number captures viewing that happened during the broadcast window and so rewards spectacle; it does not by itself predict sustainable week-to-week performance in a fragmented market, where the average late night episode sits substantially lower, as the 2.69 million live+7 figure demonstrates.
Implications for late night and talent economics
Colbert’s finale underlines a persistent reality: established hosts who can mobilise celebrity networks and create a feeling of cultural moment still command leverage. That has consequences for contract negotiations, production budgets and the kinds of segments networks prioritise. Broadcasters will look at the finale as evidence that premium, appointment-focused content can break through, but they must balance the costs of producing those moments against the limited frequency with which they deliver comparable returns.
A final note on legacy
Colbert leaves behind a programme that mixed political satire, celebrity interviews and musical variety, and the finale was consciously celebratory of that hybrid. While critics on the right have long argued that late night leans liberal in tone, the episode’s strong ratings should give pause to anyone who assumes ideological bias alone determines viewership. The numbers suggest a broader appetite for well-produced television events, regardless of host viewpoint, provided those events are sold as national moments rather than ordinary episodes.
