American, origin unclear, perhaps onomatopoeic of blather; perhaps adaptation of dialectal speech, perhaps from yatata or yatter. Various variant forms appear in the US 1940s–60s; for example, the 1947 American musical Allegro by Oscar Hammerstein II and Richard Rodgers contains a song called “Yatata, Yatata, Yatata,” about cocktail party chatter; see talk page for additional citations.
Popularized in the United States in the late 1990s by TV show Seinfeld, where it appears as a catchphrase, initially in Season 8, Episode 19, entitled “The Yada Yada”, originally aired on April 24, 1997, which centers around the phrase (in the duplicative “yada yada” form).
Sometimes popularly attributed to Yiddish, but this is dismissed by etymologists. It is perhaps derived from the Norwegian expression "Jada, Jada" which has a similar interpretation.
