Late-night talk shows are among the most sacred and long-running traditions in television. Ever since Steve Allen started NBC’s The Tonight Show in 1954, television audiences have ended their days watching an amiable comedian, dressed in a suit, making jokes about the news of the day, interviewing celebrities, and indulging in various bits of variety entertainment and comedy. It is a formula that has only become more and more common in the years since. That format, however, would undergo a change the likes of which the world had never seen on February 1st, 1982, at 12:30 A.M., when the world was introduced to Late Night with David Letterman, changing the course of late-night television and comedy forever.

When Late Night premiered, Johnny Carson had been the permanent host of The Tonight Show for twenty years. Watching Carson was part of the nightly routine for millions of Americans. He was the quintessential late-night host. He had a charismatic, charming likability, and his comedy stylings appealed to a wide audience. He started as a comedian and game show host before taking over The Tonight Show in the early 1960s, where America fell in love with him almost immediately. David Letterman, on the other hand, had a less traditional path to success. Born in Indiana, Letterman worked as a radio broadcaster and local television weatherman before moving to Los Angeles to pursue stand-up comedy. Letterman had a dry, sarcastic, and somewhat awkward style of comedy that led to multiple opportunities in entertainment, such as writing and performing on specials as well as other projects that failed to materialize, including pilots for game shows that were not picked up, and even an audition for the lead role of Ted Striker in the comedy classic Airplane!

While Letterman’s humor did not work for everyone, it did work on the King of Late Night himself, Johnny Carson. Letterman appeared multiple times on The Tonight Show in the late 1970s/early 1980s, and even served as a recurring guest host. His appearances on The Tonight Show would lead to his first big break in 1980, when he was given his own morning show. The David Letterman Show was truly something never seen before. During a time slot that was mostly dedicated to game shows and daytime talk shows, The David Letterman Show became an early showcase of the chaotic, wacky, and deconstructionist style of comedy that would later make Letterman a hit in late-night. The David Letterman Show was well received by critics and its audience; however, it was not a ratings success, and many felt the show’s content was out of place in the morning/daytime slot. It was canceled in October of 1980, less than six months after its premiere. Even though Letterman was undoubtedly funny, his unconventional approach to the genre ultimately alienated many television viewers who seemingly did not get it. 

Although the daytime show was not a hit, NBC knew they had a real talent with Letterman, keeping him under contract and as guest host of Tonight before giving him the 12:30 A.M. slot after Carson. Letterman’s sarcastic, offbeat humor appealed to younger viewers, especially college-aged viewers who were more likely to stay up late into the night. Letterman was always a fan of Johnny Carson and had a deep respect for him, but in many ways, he was the “anti-Carson.” Letterman (and his show in general) was not as polished as the typical Tonight Show tradition. He had curly hair, thick glasses, wore a suit, but would frequently take off his jacket at any chance he got, and would wear khaki pants and sneakers. He had unconventional guests, including Andy Kaufman, Harvey Pekar, and Pee-Wee Herman. He had segments dedicated to dropping things off of buildings, and even wore a velcro suit and jumped onto a velcro wall to stick to it. He introduced the world to silly characters such as Larry “Bud” Melman. He had a well-known disdain for authority figures, especially the higher-ups at NBC, frequently mocking them on air, which led many of these executives to dislike Letterman. His house band, “The World’s Most Dangerous Band” (later “The CBS Orchestra”) led by Paul Shaffer, offered a much more diverse and eclectic sound. Letterman’s monologues were also untraditional and much shorter than those of other hosts, dedicating more time to his remote segments and “desk bits,” such as his nightly “Top Ten List,” which he continued until his retirement from The Late Show on CBS. In terms of his interviewing style, Letterman was known, and in some cases infamous, for never shying away from making fun of his guests or making his disinterest toward them known. Letterman had many feuds and uncomfortable exchanges with various celebrities, some of which he has expressed remorse for in years past. Letterman would frequently make jokes at his own expense and at the expense of the show, especially on nights that he felt were particularly rough. This acerbic style was groundbreaking for television at the time. David Letterman did to late-night comedy in the 1980s what Steve Martin did to stand-up comedy in the 1970s. Late Night with David Letterman was a complete deconstruction of the typical late-night talk show.

David Letterman continued to host Late Night until 1993 before moving to CBS after Jay Leno was selected to take over for Johnny Carson as the host of The Tonight Show, but that is a topic for another blog. Letterman was devastated when he did not get The Tonight Show, and so were many late-night comedy fans. Hosting Late Night for ten years at the time of Carson’s retirement, many saw Letterman in line to take over Tonight, including Johnny Carson. Rather than stay at 12:30, Letterman moved up (and over about three or four blocks) to host The Late Show with David Letterman weeknights at 11:30, at the Ed Sullivan Theater, on CBS. Although he did not get the coveted Tonight Show, Letterman was given a venue to showcase his style of comedy. Continuing his signature bits such as “Stupid Pet Tricks” and the nightly “Top Ten,” as well as new segments like “Will It Float,” in which an object is dropped into a large container of water with Letterman and Shaffer predicting whether the object would sink or float. It can absolutely be argued that NBC’s decision to give The Tonight Show to Jay Leno helped Letterman in a way by allowing him to continue to do his distinct style of comedy for which he is known. The Late Show would run until Letterman’s retirement in 2015, marking thirty-three years on air, the longest serving late-night talk show host in American history. Stephen Colbert would serve as host of The Late Show before being canceled in 2026 due to CBS’s capitulation to the fascist Trump regime. Letterman’s status as the original host of both Late Night on NBC and The Late Show on CBS further displays his iconic status in the history of late-night television.

Since leaving the desk in 2015, Letterman has continued working, hosting the in-depth interview talk show My Next Guest Needs No Introduction on Netflix. He continues to make appearances on other talk shows, award shows, and comedy festivals. He has recently been a vocal critic of Donald Trump and has consistently stood up for the current late-night hosts as they defend their right to satirize the President. Letterman is frequently named as an influence by comedians and talk show hosts, most notably Conan O’Brien, Jimmy Kimmel, and Tom Green, who famously hosted his own satirical talk show in the 2000s. Conan O’Brien has notably praised Letterman, crediting him with helping him early on in his career when Letterman appeared on Late Night with Conan O’Brien, early in its run. Conan credits Letterman’s grace and humor on that appearance with helping audiences see Conan’s comedic legitimacy. O’Brien also credits much of his comedy style to Letterman, as he too, has become a popular figure in late-night history, known for his chaotic and wacky style similar to Letterman’s.

Late night television as a genre is going through tough times. Along with the political tension, the shows have also seen a dip in ratings and a decline in cultural relevance. As a fan of the late-night genre, I believe another late-night shake-up, such as the one Letterman ushered in in 1982, is much needed. Still, Letterman’s influence as a deconstructionist can be seen in comedy today. In the 2010s, shows such as The Eric Andre Show and Between Two Ferns with Zach Galifianakis also served as deconstructions of the late-night genre. In today’s podcast age, shows such as The Adam Friedland Show and Office Hours Live with Tim Heidecker are giving podcasts the Letterman treatment, satirizing the medium as it has become a force within the media landscape. 

David Letterman is a legend and a pioneer in comedy for his subversive, irreverent approach to his show and to late-night television as a whole. He brought silliness to the airwaves and paved the way for generations of satirical, self-referential comedians who seek to shake up the traditional genre conventions of their respective mediums. His influence in comedy will last forever.
