Jay Leno vs. David Letterman vs. Jimmy Kimmel vs. Conan O'Brien vs. Craig Ferguson

I faced off five late-night talk show hosts in the US.



Overall, Leno was king of late night though Letterman occasionally peaked higher. Both also displayed a slight downward trend whereas Kimmel and Ferguson were slowly gaining Google-popularity over the years. O'Brien's trend was the most stable. By the way, the best movie about the US late-night talk show phenomenon is The Late Shift.
