American TV legend Letterman bids farewell

The king of late-night American television, David Letterman, broadcasts his final show on May 20, ending a 33-year run of unpredictable, caustic comedy that set him apart.

The longest-serving nighttime talk show host on U.S. television with more than 6,000 shows to his name, 68-year-old Letterman has been honored with tributes in the U.S. media, and by a host of celebrities.
