More on the state of print newspapers

This article wonders why more papers have not gone under as it shows that inflation adjusted newspaper advertising revenue today is equal to what it was in 1950.  One person commenting states that "Advertising revenue includes classified ads -- Craigslist takes away a huge chunk of this newspaper profit center."  I can't imagine this would be a huge chunk of profits.  Thoughts?  From someone who had a bad incident advertising on Craigslist recently, I'm going back to advertising in the newspaper.  Guess there could be freaks out there as well who read the paper but this was just ridiculous!  The article by Mathew Ingram on The Atlantic states that digital ad revenue has increased 50% this year alone.  I doubt many will be with me in reverting to using print advertising.
