The Tonight Show is a long-running American late-night talk show on NBC, with Jimmy Fallon as host since 2014. Its opening sequence, backed by the show's house band, is designed to welcome the audience and introduce Fallon to the studio crowd. Clips of television openings like this are widely shared online by creators who want an instant, recognisable broadcast feel for sketches, reaction videos and parodies. The format has stayed familiar for years, which is why a short intro sting still works as shorthand for a polished late-night show.
