Mads Eriksen was born in Malvik and lives and works in Trondheim. He is best known as the creator of the comic strip 'M', but he began his career with the comic 'Gnom' in Smult magazine in 2000. When this magazine folded, he got the opportunity to introduce his semi-autobiographical 'M' comic as a guest strip in Pondus magazine.
It got a spot in Dagbladet in 2002, replacing the 'Hagar the Horrible' strip. Eriksen's 'M' quickly established a large fanbase for its humour and pop-cultural references and got its own monthly comic book published by Schibstedforlagene in late 2006, while it is also still running in Dagbladet and Adresseavisen.
