A generic name for the Internet.
A proposed high-speed communications system that was touted by the Clinton/Gore administration to enhance education in America in the 21st century. Its purpose was to help all citizens regardless of their income level. The Internet was originally cited as a model for this superhighway; however, with the explosion of the Web, the Internet became the information superhighway whether it was ready for it or not.
