A major driver of Internet growth has been the USA's decades-long national policy of funding basic research and infrastructure prototyping in its universities. This unique national system has enabled universities to experiment with capabilities years ahead of their mass commercial distribution. From Arpanet to NSFnet, this far-reaching partnership between government, universities and industry planted the seeds that grew into the modern cyberworld. More recently, NCSA Mosaic and NCSA's Web server software catalyzed the development of the World Wide Web. This "explore the future" methodology has been institutionalized in the National Science Foundation's Partnerships for Advanced Computational Infrastructure (PACI) program. Each PACI partnership brings together dozens of leading researchers at some 75 institutions to create the services necessary to prototype a seamless, integrated computational and collaborative environment known as the Grid.
