A Report from The Guardian outlining the baby steps The Booker prize is taking towards going digital:
With a fair degree of inevitability, the Booker prize is going digital. It has just been announced that extracts from this year’s shortlistwill be available over your mobile phone immediately the nominees are announced on September 9. You’ll be able to get the extracts as either audio or text (though, hopefully, not text-speak).
The emphasis appears to be on audio-books rather than e-books; probably out of recognition that most current cellphones have crap screens.
