With the unsurprising news that The New York Times Company is trying, once again, to part with The Boston Globe, we see the start of a wave of likely change in metro newspaper ownership across the United States. When the Globe changes hands, and when Tribune puts its metros on the block, readers in Boston, Baltimore, Chicago, Los Angeles, Hartford, Orlando and South Florida will all see change. They’ll join readers in Tampa, Chicago, Orange County, San Diego, and Philadelphia, who have had new owners take over the local presses recently. Add in readers in Denver and Seattle, who lost one of their two papers completely. It’s astounding, really.
