WNET, branded on air as Thirteen, is New York City's flagship public television station and a major PBS member station, so its logo sting has been heard by generations of viewers at the start and end of programmes. The two-second ident became a piece of broadcast nostalgia in its own right, separate from any single show, and short audio clips of it now circulate on soundboards and in video edits. Creators keep using it because it instantly signals public television, formality and a bygone era of scheduled broadcasting, even in a joke or parody context.
