It's difficult to imagine life without the Web, even though a large majority of Americans spent part or most of their lives without it. But it was only 25 years ago this week that British computer scientist Tim Berners-Lee published the proposal that is widely considered to be the birth of the World Wide Web.
When Berners-Lee published "Information Management: A Proposal" at the European Organization for Nuclear Research, he set out to achieve a practical goal: to make the troves of information at CERN more accessible to the institute's scientists by using hypertext to share information. Instead, he touched off a revolution.
Today, more than 2.7 billion people around the world acess the Web. Here is a look back at the Word Wide Web's meteoric rise since 1989.
1990: Berners-Lee develops the first Web page and server, naming it the WorldWideWeb, on a NeXT computer for scientists at CERN.

1993: On April 30, CERN makes the WorldWideWeb software available to the public. The Massachusetts Institute of Technology's student newspaper, The Tech, is the first newspaper to develop a web presence. In December, The New York Times publishes its first article about the Web, in which the print paper describes Mosaic, one of the earliest Internet browsers, as a "map to the buried treasures of the Information Age."
1994: Netscape—the brainchild of Marc Andreessen and Jim Clark—launches. Yahoo also gets its start this year, and the first banner ad appears. By the end of the year, there are 11 million Americans online and the White House and United Nations are both online. Tim Berners-Lee founds the World Wide Web Consortium (W3C) to create worldwide standards for the Web.
1995: Microsoft introduces the new Web browser, Internet Explorer, setting off a "browser war" with Netscape. Jeff Bezos and Pierre Omidyar touch off the e-commerce revolution with the launches of Amazon and eBay.
