BBC’s free iPlayer not only offers downloads of the past week of the TV network’s programs but also the listeners’ own choice of podcasts, tentatively called MyBBCRadio. Yet to come: details of how do-it-yourself scheduling will work. Meanwhile this week, the Beeb is offering downloads of BBC Philharmonic performances of Beethoven’s symphonies 6 through 9. Music lovers downloaded the first five symphonies 700,000 times. Downloads are offered for a week starting on the day after broadcast. The iPlayer holds down server costs by using Kontiki peer-to-peer technology also employed by the California-based nonprofit Open Media Network.
