In 1972, Marvel set up a publishing arm in the UK, Marvel UK, reprinting American superhero strips. These proved extremely popular, and a range of weekly titles was being published by 1975. So much so that in 1976 the parent company briefly published a minimal amount of new material specifically for the UK market in "Captain Britain". The American reprint material proved to be more successful and continued to appear into the 1980s, at which stage Marvel UK also began diversifying into home-produced original material, both UK-originated strips featuring American created characters such as Captain Britain, the Hulk and the Black Knight, and wholly original strips like "Night Raven". They also began producing television-based material, initially with "Doctor Who Weekly", launched in 1979.
