David Letterman’s final “Late Show” show aired on May 20th. The popular comedian hosted a late-night TV talk show for 33 years, the longest reign of any late-night host. Throughout his long career, Letterman had the responsibility of keeping American’s spirits light through a lot of change in the United States, including during the events of September 11. And while many aspects of the show stayed the same across the decades, Letterman himself adapted and helped keep the show alive.
