redletterdave writes "Popular gaming magazine GamePro has shut down its U.S. operations after 22 years of publications by its parent company IDG. GamePro's website, which has been online for about 13 years, will be converted to a gaming channel and incorporated into PCWorld on Dec. 5. Sources within the magazine say GamePro's employees, including its executives, received phone calls this morning with the news. The news comes as a relative surprise, as GamePro experienced its highest traffic ever last week. The company also released its first quarterly magazine earlier this month after deciding monthly print issues were too costly to maintain."
