With all the technology improvements to the Web over the last several years, it’s hard to believe that the Web is still in its infancy. Despite popular belief, Mosaic (later changed to Netscape Navigator) was not the first Web browser. Mosaic was released in 1993 and was simply the first popular one used by the general public. The first Web browser, known as WorldWideWeb (see screenshot below), was invented by Tim Berners-Lee in February 1991, the same guy who invented HTTP (hypertext transfer protocol) in 1989. WorldWideWeb, later renamed Nexus, ran on the NeXTSTEP platform, which of course was formed by Apple’s Steve Jobs. 
Berners-Lee developed the software on his NeXTcube while working for CERN. The original code still resides on that NeXTcube in the CERN museum. Unfortunately, we’ll never get to see that code, because the computer is a historical artifact. While we were still using technology like Gopher, FTP, Usenet and various text-based BBS systems to access the Web (prior to the WWW), large corporations jumped on the bandwagon early. The oldest registered domain name was SYMBOLICS.com, registered in March of 1985. It didn’t take long for other companies to catch on. In 1986, Xerox became the 7th domain registered, followed by HP (#9), IBM & Sun (#11), Intel (#13), AT&T (#15), Boeing (#26), Adobe (#42), Tandy (#50), and Unisys (#50). On February 19, 1987, Apple Computer registered Apple.com (#64). As is typical, Microsoft followed the leader and finally registered Microsoft.com in May of 1991.
