The famous aria "Largo al factotum" from "The Barber of Seville" by Gioachino Rossini was used in a 1990s television commercial for AT&T. The commercial featured the actor Jerry Seinfeld, who played the role of a struggling actor who tries to get an agent by singing the aria. The commercial was a huge success and helped to popularize the aria, which has since been used in many other commercials, television shows, and movies.
