We could make a long list of things that soon will not exist anymore because of their production costs (music CDs being one, movie discs being another). But PC Mag was one big ad mag with two horrid Dvorak columns thrown in, and since most of those advertisers' companies don't exist anymore, there's little profit in the whole enterprise.
Look at Apple Computer, er, just 'Apple' now since they don't want to be identified as a computer company anymore, and the money they make off of computers is a distant third to the profit from ipods and iphones (still no redial!). Here's another dinosaur that will have to soon reinvent itself to stay alive: radio, both satellite and terrestrial.
