"The federal government's reliance on private industry has been driven by changes in technology. Two decades ago, telephone calls and other communications traveled mostly through the air, relayed along microwave towers or bounced off satellites. The N.S.A. could vacuum up phone, fax and data traffic merely by erecting its own satellite dishes. But the fiber optics revolution has sent more and more international communications by land and undersea cable, forcing the agency to seek company cooperation to get access." -- Andrew Councill, "Wider Spying Fuels Aid Plan for Telecom Industry" The New York Times, 2007-12-16
