One super cool BBC site: Cult Television - TV, DVD and lovely stuff: news, reviews and fun. As they say the site is full of great stuff: fashion, film, music, TV, toys, photo galleries, quizzes, trailers, trivia, reviews and much, much more information. What you have to see there: I Love... by Year from 1960s to 1990s; Classic TV; Sherlock Holmes; and 2000AD and British Comics. It's not super cool, it's wonderful.
Update: Check also Doctor Who: rare and acclaimed Doctor Who novels available to read for free.
