So here’s a prediction: long before the Berkshire Hathaway warrants expire, many of the papers Buffett has invested in will have reduced both print days and their newsroom staff, and journalists will be writing the “What went wrong with the Media General deal?” story.The answer to that question is already apparent: Buffett wants to talk like a philanthropist and an investor at the same time, not understanding that the public good and the bottom line have diverged. A newspaper used to be both a profitable business and a public service, but this was just an accident of the competitive (or rather uncompetitive) media landscape. His commonsense approach to saving papers won’t work, because there is no longer any commonsense business model for a former monopoly that is still seeing its revenues erode faster than its costs.
