Billionaire Warren Buffett's company is making its largest foray into newspapers yet, agreeing to buy 63 papers from Media General Inc. The $142 million deal includes the Richmond Times-Dispatch and the Winston-Salem Journal. The company is selling all its papers except those in Tampa, most importantly the Tampa Tribune. Media General says it is in talks with others for those papers. Buffett's Berkshire Hathaway has owned the Buffalo News for decades and recently bought its hometown paper, the Omaha World-Herald.
