Thorpe & Porter went bankrupt in 1966 and was purchased by the distribution arm of DC Comics, then known as IND. As a result, T & P's output became almost exclusively reprints of DC titles. Marvel Comics superhero reprints appeared in Odhams Press' Power Comics line in 1966–1969, overlapping for a period with Alan Class Comics' reprinting of some of Marvel's superhero characters. Marvel reprints also appeared in City Magazines' "TV21" in 1970–1971. And in 1972 Marvel launched Marvel UK, cornering the market on Marvel reprints; key titles included "The Mighty World of Marvel" and "Spider-Man Comics Weekly". The importation of Marvel's American comics continued to be erratic due to Marvel UK's promotion of their own reprints, which meant some titles were not offered for periods — "The Amazing Spider-Man" being a prime example.
