Media convergence

In an interesting example of media convergence, The Economist has made its entire magazine available in audio format.
From their site, "the audio edition contains word-for-word recordings of all articles published in The Economist, read by professional broadcasters and actors. It is ideal for anyone who wants to listen to articles while travelling, exercising or just relaxing."
If you subscribe to the magazine, the audio is free. If you don't then you can purchase each edition for US$8.
I think this is a brilliant idea, partly because it takes great content and broadens the reach through a very relevant channel, partly because it adds value for their existing customers, and partly because as one the first major publishers to do this, they will surely benefit from a spike in readers/listeners from people curious to sample this new format.
Good luck to them. Have a look here.
