The Wayne's World sketches on Saturday Night Live, chronicling the adventures of metalhead Wayne Campbell and his friend Garth Algar as they hosted a public-access television show from his parents' basement, ran from 1989 to 1994 (the character having originated on the CBC variety series It's Only Rock & Roll two years earlier), inspiring the surprise hit film of the same name in 1992 (by some distance the most successful film based on an SNL sketch) and its sequel a year later.

DEF II was an early-evening programming strand aimed at teenagers which broadcast twice weekly between 1988 and 1994. It frequently featured American imports ranging from The Fresh Prince of Bel-Air to Mission: Impossible, and, yes, in 1992 the Wayne's World sketches were the first Saturday Night Live material to be seen on the BBC.
