Sargent was a dominant figure at the Proms in the post-war era. He was chief conductor of the Proms from 1947 until his death in 1967, taking part in 514 concerts. A 1947 Prom under his baton was the first concert to be televised in Britain. As conductor of the Proms, Sargent gained his widest fame, making the "Last Night" of each season into a high-ratings broadcast celebration aimed at ordinary audiences, a popular, theatrical flag-waving extravaganza presided over by himself. He was noted for his witty addresses in which he good-naturedly chided the noisy promenaders. In his programmes he often conducted choral music and music by British composers, but his range was broad: the BBC's official history of the Proms lists selected programmes from this period showing Sargent conducting works by Bach, Sibelius, Dvořák, Berlioz, Rachmaninoff, Rimsky-Korsakov, Richard Strauss and Kodály in three successive programmes. During his chief conductorship, prestigious foreign conductors and orchestras began to perform regularly at the Proms. In his first season in charge, Sargent and two assistant conductors conducted all the concerts among them; by 1966 there were Sargent and 25 other conductors. Those making their Prom debuts in the Sargent years included Carlo Maria Giulini, Georg Solti, Leopold Stokowski, Rudolf Kempe, Pierre Boulez and Bernard Haitink.
