Colbert and Letterman: Core Facts and Career Timelines
Stephen Colbert hosts The Late Show on CBS, and David Letterman hosted Late Show with David Letterman on CBS until 2015, followed by hosting My Next Guest Needs No Introduction on Netflix. Colbert moved from Comedy Central's The Colbert Report to CBS in 2015, while Letterman retired from CBS in May 2015 after a 33-year run across NBC and CBS. Both hosts built long-running franchises that generated significant advertising revenue and shaped late night television ratings and production costs.
Letterman started Late Night with David Letterman on NBC in 1982 before moving to CBS in 1993. Colbert launched The Colbert Report on Comedy Central in 2005 and took over The Late Show from Letterman on CBS in September 2015. According to public reports, Letterman's final CBS contract was worth roughly $150 million over two years, while Colbert's CBS deal was reported near $100 million over multiple years, reflecting the high cost of late night talent and the value networks place on late night franchises.
Ratings, Audience Data, and Advertising Impact
Late night ratings are tracked by Nielsen, and the late night lineup is a key battleground for advertisers targeting adults 18-49. In recent seasons, The Tonight Show Starring Jimmy Fallon has often led in total viewers, while Colbert has competed closely in the key adult demographic, with ratings fluctuating based on political events, interviews, and viral clips shared on platforms like YouTube and X.
Advertising rates in late night depend on ratings, with 30-second spots often priced in the tens of thousands of dollars per airing. Networks use late night shows to promote their broader prime time and streaming slates, and viral moments from Colbert and Letterman segments frequently drive tune-in and online engagement, which supports ad pricing and brand partnerships across the CBS and Netflix platforms.
Business Models, Streaming, and Corporate Context
CBS is part of Paramount Global, which also operates Paramount+, while Netflix is a public company trading on the NASDAQ under NFLX and reports quarterly earnings that include subscriber growth and content spending. Letterman's Netflix series is part of Netflix's broader strategy to invest in prestige talk and comedy content, while Colbert's CBS show supports the CBS late night schedule and cross-promotion with other Paramount assets.
Late night production involves significant costs for writing staff, guest booking, and live or taped episodes, with shows typically recording multiple episodes per week. Both Colbert and Letterman operate within union agreements, and their shows contribute to the broader media ecosystem that includes digital clips, podcast extensions, and brand integrations, which are increasingly important revenue streams for networks and streaming platforms.
