The Web browser turns 15 on Oct. 13, 2009 - a key milestone in the history of the Internet. That’s when the first commercial Web browser - eventually called Netscape Navigator - was released as beta code. While researchers including World Wide Web inventor Tim Berners-Lee and a team at the National Center for Supercomputing Applications created Unix browsers between 1991 and 1994, Netscape Navigator made this small piece of desktop software a household name.
