Business Week has an interesting piece about podcasting, which points out that what had been a medium for new voices may be taken over by traditional media companies encouraged the arrival of Apple's iTMS. Movie reviewers Adam Kempenaar and Sam Hallgren, for example, now have to compete with Ebert & Roeper from the Chicago Sun-Times.
"Apple's service, though just over a month old, is already changing the dynamics of the field. It has helped legitimize the medium, drawing traditional giants, from Ebert & Roeper parent Walt Disney to Dow Jones and News Corp. As they join iTunes, they're squeezing out many of the do-it-yourselfers who evangelized podcasting. Once a podcast drops off the top 100 list, it's almost impossible for a casual visitor to find it. For Kempenaar, the future is clear: "It will be harder for a new indie podcaster to get an audience."
This is not, of course, the end of the story....
