Spider-Man Comics Weekly was a Marvel UK publication which primarily published black-and-white reprints of American Marvel four-color Spider-Man stories. Marvel UK's second-ever title, Spider-Man Comics Weekly debuted in 1973, initially publishing "classic" 1960s Spider-Man stories (as well as Thor backup stories).
The title proved to be a great success. Along with Marvel UK's flagship title, The Mighty World of Marvel, Spider-Man Comics Weekly helped Marvel gain a foothold in the (at the time) vast UK weekly comic market, allowing the company to cross-market and later introduce non-superhero UK-reprint titles such as Planet of the Apes and Star Wars.
Although it changed its title name several times over the years (mostly due to other less successful Marvel UK comics merging with it), the Spider-Man weekly comic eventually became the longest-running Marvel UK publication, publishing 666 issues from 1973 to 1985.
