Debut of Late Show with David Letterman on CBS

On August 30, 1993, David Letterman made his highly anticipated debut on CBS with the 'Late Show with David Letterman,' marking a significant moment in late-night television history. The show was filmed at the iconic Ed Sullivan Theater, a venue rich in entertainment history, which underwent an extensive $8 million renovation to accommodate Letterman's arrival. CBS secured Letterman with a lucrative three-year contract worth $14 million per year, effectively doubling his previous salary from NBC. While the 'Late Show' retained Letterman's signature humor and innovative style, it also introduced new elements, such as a lengthened monologue. Paul Shaffer and the World's Most Dangerous Band transitioned to CBS, rebranded as the CBS Orchestra. Due to intellectual property disputes, several beloved segments from his NBC days were renamed, including the 'Top Ten List' becoming the 'Late Show Top Ten' and 'Viewer Mail' evolving into the 'CBS Mailbag.' Despite these changes, Letterman's unique approach to comedy and his rigorous formalism continued to engage and entertain audiences, solidifying his place in late-night television lore.
