A confession: we can't keep up with the media congomerates, and are always forgetting who owns Us Weekly. Here are a set of links to useful data and charts. Still missing: a database which, when a magazine title or TV network is plugged in to the search box, produces the parent company in the result.
· Big Ten [a chart, from The Nation]
· Who Owns What [exhaustive listing, from the CJR]
· Media Ownership 2001 [a graphical indictment of media concentration, from mediachannel.org]
· 100 leading media companies [ranked by revenue, from Advertising Age]
· Media giants [a chart, from PBS]
· Resources [a list of other databases, tables and charts, from I Want Media]
