“The Mosaic browser started out in 1993 with twelve users, and I knew all twelve,” said Andreessen. There were only about fifty Web sites at the time and they were mostly just single Web pages. “Mosaic,” he explained, “was funded by the National Science Foundation. The money wasn't actually allocated to build Mosaic. Our specific group was to build software that would enable scientists to use supercomputers that were in remote locations, and to connect to them by the NSF network. So we built [the first browsers as] software tools to enable researchers to 'browse' each other's research. I looked at it as a positive feedback loop: The more people had the browser, the more people would want to be interconnected, and the more incentive there would be to create content and applications and tools. Once that kind of thing gets started, it just takes off and virtually nothing can stop it. When you are developing it, you are not sure anyone is going to use it, but once it started we realized that if anyone is going to use it everyone is going to use it, and the only question then was how fast it would spread and what would be the barriers along the way.”
Indeed, everyone who tried the browser, including Barksdale, had the same initial reaction: Wow! “Every summer, Fortune magazine had an article about the twenty-five coolest companies around,” Barksdale recalled. “That year [1994] Mosaic was one of them. I not only had read about Clark and Andreessen but had turned to my wife and said, 'Honey, this a great idea.' And then just a few weeks later I get this call from the headhunter. So I went down and spoke to Doerr and Jim Clark, and I began using the beta version of the Mosaic browser. I became more and more intrigued the more I used it.” Since the late 1980s, people had been putting up databases with Internet access. Barksdale said that after speaking to Doerr and Clark, he went home, gathered his three children around his computer, and asked them each to suggest a topic he could browse the Internet for-and wowed them by coming up with something for each of them. “That convinced me,” said Barksdale. “So I called back the headhunter and said, Tm your man.'”
Netscape's first commercial browser-which could work on an IBM PC, an Apple Macintosh, or a Unix computer-was released in December 1994, and within a year it completely dominated the market. You could download Netscape for free if you were in education or a nonprofit. If you were an individual, you could evaluate the software for free to your heart's content and buy it on disk if you wanted it. If you were a company, you could evaluate the software for ninety days. “The underlying rationale,” said Andreessen, “was: If you can afford to pay for it, please do so. If not, use it anyway.” Why? Because all the free usage stimulated a massive growth in the network, which was valuable to all the paying customers. It worked.
We put up the Netscape browser, said barksdale, and people were downloading it for three-month trials. I've never seen volume like this. For big businesses and government it was allowing them to connect and unlock all their information, and the point-and-click system that Marc Andreessen invented allowed mere mortals to use it, not just scientists. And that made it a true revolution. And we said, 'This thing will just grow and grow and grow.'“
Nothing did stop it, and that is why Netscape played another hugely important flattening role: It helped make the Internet truly interoperable. You will recall that in the Berlin Wall-PC-Windows phase, individuals who had e-mail and companies that had internal e-mail could not connect very far. The first Cisco Internet router, in fact, was built by a husband and wife at Stanford who wanted to exchange e-mail; one was working off a mainframe and the other on a PC, and they couldn't connect. “The corporate networks at the time were proprietary and disconnected from each other,” said Andreessen. “Each one had its own formats, data protocols, and different ways of doing content. So there were all these islands of information out there that were disconnected. And as the Internet emerged as a public, commercial venture, there was a real danger that it would emerge in the same disconnected way.”
