WASHINGTON -- The WorldCom accounting scandal has tarnished the company's reputation and could possibly lead it into bankruptcy. Unlike many recent telecom headline-makers, however, WorldCom operates an established voice and data network with significant market share and revenue. Specifically, WorldCom's UUNet business unit generated $4.7 billion in Internet revenues from access and hosting in 2001, three times more than its closest competitor. Although WorldCom offers a huge range of Internet services, its backbone access operation occupies a particularly strong position in the market. "WorldCom is the largest Internet backbone on many levels including its expansive, international network, large customer and revenue base, and rich interconnection relationships," said Alan Mauldin, Research Analyst at TeleGeography. As a result, WorldCom is able to charge a premium for connectivity to its network -- an enviable position for any Internet services company, particularly when its rivals are engaged in a price war. Although WorldCom CEO John Sidgemore has denied plans to sell off UUNet, the decision to do so may ultimately belong to the company's creditors. Valuing UUNet and understanding its role in national infrastructure will not be simple, however. Ferocious competition, rapid network deployment, and turbulent market conditions have made the U.S. backbone a complex snarl of overlapping networks. TeleGeography's latest research on U.S. backbone deployments untangles the mess and provides the most comprehensive view available of how WorldCom stacks up against the competition.
