Late Show with David Letterman

Late Show with David Letterman is an American late-night talk show hosted by David Letterman on CBS, the first iteration of the Late Show franchise. The show debuted on August 30, 1993, and was produced by Letterman's production company, Worldwide Pants, and CBS Television Studios. The show's music director and leader of the house band, the CBS Orchestra, was Paul Shaffer. The head writer was Matt Roberts and the announcer was originally Bill Wendell, then Alan Kalter. In most American markets, the show aired from 11:35 p.m. to 12:37 a.m. Eastern and Pacific Time, and recorded Monday to Wednesdays at 4:30 p.m., and Thursdays at 3:30 p.m. and 6:00 p.m. Eastern Time. The second Thursday episode usually aired on Friday of that week.

In 2002, Late Show with David Letterman was ranked No. 7 on TV Guide's 50 Greatest TV Shows of All Time. As host of both Late Night and Late Show for more than 30 years, Letterman surpassed Johnny Carson as the longest running late-night talk show host in 2013. That same year, Late Night and Late Show were ranked at No. 41 on TV Guide's 60 Best Series of All Time. The show was nominated for the Primetime Emmy Award for Outstanding Variety Series 16 times, winning 6. It was also nominated for the Primetime Emmy Award for Outstanding Directing for a Variety Series 15 times, and was nominated for the Primetime Emmy Award for Outstanding Writing for a Variety Series 16 times during its run.

In 2014, Letterman announced his retirement; the final episode of Late Show aired on May 20, 2015. After Letterman's final Late Show, instead of airing reruns of the show or having guest host episodes of Late Show, CBS opted to air reruns of scripted dramas in the 11:35 pm time slot over the summer with the branding CBS Summer Showcase. The show was then succeeded by The Late Show with Stephen Colbert, hosted by Stephen Colbert, which premiered on September 8, 2015.

CBS had previously attempted late-night talk shows with The Merv Griffin Show (1969–1972) and The Pat Sajak Show (1989–1990), but Griffin clashed with network censors and moved to syndication while Sajak was unable to compete with NBC's The Tonight Show Starring Johnny Carson and was canceled due to poor ratings. For most of the 20 years preceding Late Show, CBS's late night fare consisted of movies, reruns and specialty programming packaged under the name CBS Late Night and broadcast to middling ratings. When David Letterman became available following a conflict with NBC, CBS was eager to lure him and offered him a three-year, $14 million per year contract, doubling his Late Night salary. According to their agreement, the show would spend a month in Hollywood at least once a year.

CBS purchased the Ed Sullivan Theater for $4 million, spending "several million" to renovate it. The renovation was supervised by architect James Polshek. CBS' total cost for acquiring the show including renovations, negotiation rights paid to NBC, signing Letterman, announcer Bill Wendell, Shaffer, the writers and the band was over $140 million.

A significant issue regarding Letterman's move to CBS was the ownership of long-running comedy bits used on Late Night, as well as the name of the CBS show itself. NBC claimed that much of what he did on Late Night was intellectual property of the network. Letterman and his attorneys countered that some segments ("Stupid Pet Tricks", for example) pre-dated Late Night and had first aired on The David Letterman Show, which was owned by Letterman's production company rather than NBC, and others, such as the Top Ten List and Viewer Mail, were not eligible for intellectual property protection and belonged neither to Letterman nor NBC. Ultimately a compromise was reached in key areas: the "Viewer Mail" segment would be called the "CBS Mailbag"; the actor portraying Larry "Bud" Melman on Late Night would use his real name, Calvert DeForest, on the CBS show; and Paul Shaffer's "World's Most Dangerous Band" would become the "CBS Orchestra".

NBC gave Letterman the choice of at least two options to name his new show, Late Show with David Letterman or Nightly with David Letterman. On this matter CBS executives stepped in, rejecting Nightly in part because of potential confusion with Nightline on ABC, along with the NBC Nightly News. Thus, Late Show with David Letterman quickly became the official name.

After Letterman was introduced on Late Show's very first episode, NBC Nightly News anchor Tom Brokaw accompanied him on stage and wished him "reasonably well". As part of a pre-arranged act, Brokaw then proceeded to retrieve a pair of cue cards while stating that "These last two jokes are the intellectual property of NBC!" After he carried them off stage, Letterman responded, "Who would have thought you would ever hear the words 'intellectual property' and 'NBC' in the same sentence?" In his opening monologue, Letterman said "Legally, I can continue to call myself Dave" but joked that he woke up that morning and next to him in bed was the head of a peacock (while the orchestra played the theme from The Godfather).
