Television Tie in Magazines

Official magazines for a TV show or shows. Contain interviews, spoilers, fiction etc, but rarely reviews. The television network CBS even has their own magazine for the whole network, called Watch.

One of the few that does include reviews is Doctor Who Magazine, which has been running since 1979 and is one of the best of the genre (at least in the opinion of Silent Hunter). (DWM breaks the "rarely reviews" rule, going so far as to print scathing Take Thats of Doctor Who stories, though less so since the series revival.)

If it has fiction, those bits are part of the Expanded Universe.
