The US Magazine Publishers Association has a fairly whacky, jetsonesque view of the future, if their super-slick website is any indication. Despite that they believe we'll still be reading printed mags.
Well, maybe ...
It's certainly possible to imagine some mags continuing in printed form - I know I enjoy reading NYRB and Atlantic Monthly in print. I'll scan the websites when the issue is out and print anything I absolutely can't wait to read, but then I'll wait until the copy arrives in the mail a few days later. It's just a more enjoyable experience to read their lengthy articles in the hard copy format.
Trade mags have got to be an endangered species, though.
Businessweek takes a more realistic approach to the problem. Embrace the internet and make it work for you!
But for pure inventiveness, Vodaphone's future site takes the cake.
