When David Letterman’s first ‘Late Night’ show was broadcast in August 1993, nobody could have really foreseen the way that it would change the face of late-night TV, both in the U.S. and beyond. His innovative approach to the genre not only blazed a trail for Conan, Fallon, Kimmel and many other ‘traditional’ broadcasters, but gave the viewing public an appetite for quirky, compelling, and hugely entertaining content which millions of online video creators are fulfilling.

Letterman’s very last ‘Late Show’ airs tonight (20th May) and in homage to the late-night chat show king, we present our own ‘Top Ten List’ of the most viewed Letterman clips on YouTube. 5 from the official Late Show YouTube channel, and 5 of the most viewed videos uploaded by other channels.

UPDATE: On the 11th June 2015, all video content was removed from the official Late Show channel, and the channel itself was taken offline a day later. Why? Because now the show is over, all digital rights to the video clips revert back to the show’s copyright owner – Letterman’s own TV production company, Worldwide Pants. Letterman may decide to upload these clips to another YouTube channel but until then, they remain private.

We have removed the official videos in the list but the user-generated content remains.

Top 5 Non-Letterman, Letterman YouTube Clips

#3 9-Year-Old Plays Banjo on David Letterman Show – Sleepy Man

#2 Jeff Dunham and Walter on Letterman

This upload is almost 9 years old and features Jeff Dunham and Walter on The Late Show with David Letterman from September 2006, and has attracted 11.1 million views.

#1 Adele – Make You Feel My Love (Live on Letterman)

Adele is arguably one of the most popular performers on the planet right now, and the perfect storm of a VEVO upload of a live appearance on Letterman generated an incredible 25 million views and an insane 1 million engagements (968K via Facebook online).

Interestingly, given the engagement and hype surrounding Facebook video, the team behind the Letterman show are only posting YouTube videos to the official ‘Late Show with David Letterman‘ Facebook page. They are not uploading any native video content natively to speak of, but then again, Letterman announced his retirement over a year ago, so perhaps its understandable they took their foot off the brake.

GoodBye Dave, We’ll Miss Ya!
