The Avengers was the 1960s, defining the era with its style, politics and chic. Starting in 1960 as a gritty spy drama, the programme evolved into the hippest, most fondly remembered series of the decade. The first British programme to be networked in the USA, it spawned a hit single, The New Avengers and a legacy of writers and directors who went on to shape the next 20 years of TV.
