Lookups spiked on February 7, 2014.
As Jay Leno made his final monologue as host of the Tonight Show, millions tuned in and later read reviews of the show and appreciations of Leno's 22-year tenure. Some discussions of the final broadcast included criticism of the late-night monologue format itself. For example, in The New Republic, a suggestion was made for new host Jimmy Fallon:
Leno has offered his successor one piece of advice: "Make your monologue longer...." But when Fallon takes the throne on February 17...his first step should be to reboot the format and kill the monologue entirely.
Monologue means "the routine of a stand-up comic," and originally was used refer to a long speech in a play given by one actor. It came through French from the Greek roots that mean "alone" and "to speak."
