MCI Inc.

MCI, Inc. (formerly WorldCom and MCI WorldCom) was a telecommunications company. For a time, it was the second-largest long-distance telephone company in the United States, after AT&T. WorldCom grew largely by acquiring other telecommunications companies, including MCI Communications in 1998, and filed for bankruptcy in July 2002 after an accounting scandal, in which several executives were convicted of a scheme to inflate the company's assets. These include Bernard Ebbers, who was named CEO of the company from 1985 until December 16, 2002, when he retired. WorldCom then emerged from bankruptcy under Michael Capellas, who served as its last chairman and CEO until January 2006, when the company, by then renamed MCI, was acquired by Verizon Communications and was later integrated into Verizon Business.

WorldCom was originally headquartered in Clinton, Mississippi, before moving to Ashburn, Virginia, when it changed its name to MCI.
