text: On April 3, 2012, CBS reached an agreement with Worldwide Pants and CBS Television Studios to continue the show through 2014. The parties reached another agreement in October 2013 to extend the show an additional year, continuing the series into 2015. Including his 11 years on NBC, Letterman is the longest tenured late-night talk show host, having surpassed Johnny Carson.
  On April 10, 2014, one week after Letterman announced that he would retire as host of Late Show in 2015, CBS announced that his successor as the host of the program would be Stephen Colbert, then host of competing late-night series The Colbert Report on Comedy Central. Letterman's last Late Show aired May 20, 2015. In February 2022, David Letterman's official YouTube channel opened, and contains clips from Letterman's Late Show and his previous morning and late night shows on NBC.
