In 1991 the NSFNET acceptable use policy was altered to allow commercial traffic. By 1995, with private, commercial market thriving, NSF decommissioned the NSFNET, allowing for public use of the Internet. In 1993 students and staff at the NSF-supported National Center for Supercomputing Applications (NCSA) at the University of Illinois, Urbana-Champaign, developed Mosaic, the first freely available browser to allow World Wide Web pages that include both graphics and text. Within 18 months, NCSA Mosaic becomes the Web browser of choice for more than a million users, and sets off an exponential growth in the number of Web users. In 1994 NSF, together with DARPA and NASA, launched the Digital Library Initiative.[28] One of the first six grants went to Stanford University, where two graduate students, Larry Page and Sergey Brin, began to develop a search engine that used the links between Web pages as a ranking method, which they later commercialized under the name Google.
