MEDIA BRANDS: Comcast's bid to take over Disney shows its desire to be a key player in the media world

For a while, a chart depicting the media ownership landscape hung over my desk. Produced by press watchdog Mediachannel.org and bearing a mock detergent logo with the tagline "Ultraconcentrated Media," its goal is clear: to draw attention to the fact that just a handful of companies own the vast majority of important TV networks, magazines, and publishing houses. In looking over the holdings of the then-AOL Time Warner, Vivendi, The Walt Disney Co., Bertelsmann, Viacom and News Corp., another thing is strikingly obvious. This chart, drawn up just three years ago, is already woefully out of date.
