British comics are usually comics anthologies which are typically aimed at children, and are published weekly, although some are also published on a fortnightly or monthly schedule. The two most popular British comics, "The Beano" and "The Dandy", were released by DC Thomson in the 1930s. By 1950 the weekly circulation of both reached two million. Explaining the enormous popularity of comics in British popular culture during this period, Anita O’Brien, director curator at London's Cartoon Museum, states: “When comics like "The Beano" and "Dandy" were invented back in the 1930s – and through really to the 1950s and 60s – these comics were almost the only entertainment available to children."
