Tom Johnston’s first published cartoon appeared in the Daily Mirror in 1976, and he became a full-time freelance the same year. At first his cartoons mostly appeared in the music press, including Melody Maker, Sounds and Smash Hits, but he later moved to the Evening News, then the Evening Standard. In 1981, Tom Johnston joined the Sun, and by 1989 he was the regular Cartoonist for four different newspapers and earning £150,000 a year. In 1992 he succeeded Stanley Franklin as Political Cartoonist on the Sun, moving to the Daily Mirror in 1996 to replace Charles Griffin. He enjoyed working for the tabloids, noting in 1998 that "the only difference between working for the Mirror and a broadsheet is that I no longer make many puns using literary quotations."
