I'm not sure if any other magazines have done this, but I hope it becomes a trend. According to Boing Boing, you will soon be able to buy every issue of the New Yorker ever published on a set of DVDs for $100. Imagine if Time Magazine did this. Or National Geographic. Maybe they are doing it, I think I'll find out.
Anyway, it's especially cool that it's searchable and includes all the covers, cartoons, and everything. Check out the Boing Boing mention here.
