Throughout much of the department's history, the emphasis has been on continuing productions of short-run drama serials, including adaptations of classic children's literature such as "Little Lord Fauntleroy", as well as made-for-television productions. Science-fiction has been a popular theme, from "Stranger from Space" (1951–52) through to the likes of "Dark Season" (1991) and "Century Falls" (1993). Since the middle of the 1980s, children's dramas - with the exception of the Sunday evening 'classics' slot - have almost always been screened in the weekday BBC One 3pm-5.30pm "Children's BBC" (CBBC) strand.
