Mediaweek was a New York–based trade magazine owned by e5 Global Media. It is part of Adweek Media Group, which in October 2008 announced the merging of its three separate editorial teams (Adweek, Brandweek and Mediaweek) into one.[2] In 2011, Mediaweek and Brandweek were merged into Adweek.

The chief editor was Michael Burgi.[3] Mediaweek was founded in January 1991 by BPI Publications, parent company of Billboard. The founding editors were Craig Reiss and Bill Gloede. Reiss became the editor-in-chief of parent Adweek Magazines in April of that year. Gloede became editor and remained until 2002, at which time Brian Moran, the magazine's former executive editor, moved up to editor. He was succeeded by Burgi in 2004. The magazine was initially focused on the media buying and selling communities but in 1993–94 was expanded to cover all aspects of media. Circulation was roughly half paid (the media), and half controlled (to the advertising buying community), with a total of approximately 22,000 subscribers. A two-person Washington D.C. bureau was established in 1994 and a four-person bureau was opened in Los Angeles to cover the television production studios. Ten reporters and editors were based in the New York headquarters. Until the middle 2000s, each weekly edition of the magazine featured the "Media Person" column by Lewis Grossberger, which began its life in 7 Days magazine, which was printed at the time by the publisher of the Village Voice in order to compete against New York Magazine.
