An anonymous reader writes "Mexican telephone and retail magnate Carlos Slim, in a rare defeat, will exit the U.S. consumer electronics market, shutting the last 100 CompUSA Inc. stores after sinking about $2 billion into the business. Gordon Brothers Group, a Boston-based retail store liquidator, will oversee a piecemeal sale of the Dallas-based business, the company said in a statement. Financial terms were not disclosed. Stores will remain open through year-end under the supervision of Gordon Brothers, which will also negotiate the sale of real estate and other assets. Two law firms were hired to represent creditors, CompUSA said."
