CNN owner Ted Turner was reported to be once again eyeing CBS, after its failed merger with QVC. But government regulations would probably block Turner from purchasing the "Tiffany network," according to TIME's New York correspondent Massimo Calabresi. Federal laws prohibit one company from controlling both television stations and cable systems in the same market. Turner's cable connections? Time Warner Inc. and Tele-Communications, Inc. -- both of which own stock in his company.
