As publication of Comic Art wound down, they shifted their attention to a new venture as the Thompsons started a fanzine titled Newfangles in March 1967.

[5] Thompson began working for Krause Publications as the editor of Movie Collector's World and Comics Buyer's Guide in 1983.

[citation needed] Working solo, Thompson created and edited Fantasy Empire magazine for New Media in 1981 and wrote Dark Shadows: Book Two - Lost in Thought #1-4 in 1993 for Innovation Comics.

[6] Krause later sold the movie newspaper, but Thompson continued to edit Comics Buyer's Guide, long after her husband's death in 1994[4] and the transformation of the publication into a monthly magazine.

In 2013 she began a column for San Diego Comic-Con's Toucan blog called "Maggie's World".
