Selling the World on Worldcom: John Sidgmore is point man in its Net expansion strategy

Ever since John W. Sidgmore, president of UUNET Technologies Inc., teamed up with WorldCom Chief Executive Bernard J. Ebbers, he has found that he and WorldCom are about as welcome in the telecom industry as slamdancers at the ballroom waltz. In October, WorldCom launched a hostile bid for MCI Communications Corp. and eventually wrested MCI away from British Telecommunications PLC and GTE Corp. Now, US and European regulators are threatening to scuttle the $37 billion deal because of antitrust concerns.
