How this season is filed

Twenty-One is the isolation-booth duel that ended in congressional hearings and a Hollywood movie: Stempel versus Van Doren, answers fed, living-room trust shattered. Watch it in 2026 as television's original manufactured-authenticity sin — less a game than the morality play later prestige film embalmed.

TV Flash files Season 1 of Twenty-One (1956–1958) on NBC as the desk landmark file — 2 listed hours, 1956-09-12–1957-01-01 from “Series premiere” (S01E01) to “Charles Van Doren era peak” (S01E02). Curated public milestones, not a complete season guide.
