Polystyle Publications, Ltd.
From Tardis Wiki, the free Doctor Who reference
Polystyle Publications, Ltd. was the publisher for virtually all the English-language comic strips of the 1960s and 1970s.
Polystyle purchased TV Publications, Ltd., which published TV Comics when the run of Doctor Who comic strips began. While they were in business, Polystyle published all the magazines in which Doctor Who ran, including TV Comic, Countdown, and TV Action. In 1979, Polystyle lost their license with the BBC to Marvel UK (UK), who then began publishing Doctor Who Weekly.
