In 1969, the University of California at Los Angeles and Stanford University set up a simple computer network that could send data back and forth between the two campuses. For more than 20 years, academics tinkered with this network and its successors. They used the networks to test computer technology and send research data.
In the early 1990s, commercial interest in one of the successor networks, now called the Internet, soared. Web pages popped up, and suddenly it became impractical to tinker with the network for research projects. Scientists wanted their own network again, and in 1996, created Internet2.
