Birth of the Web

A Physicist Solves an Information Problem

In 1989, Tim Berners-Lee was a physicist working at CERN (the European Organization for Nuclear Research) in Switzerland. CERN was a massive collaboration—thousands of scientists from dozens of countries, all working on the same particle physics experiments. Each group had their own documentation, databases, and systems. Finding information was hell.

Berners-Lee had already spent time managing information systems and thinking about hypertext—the idea of linking documents together. In March 1989, he submitted a proposal for an "Information Management System." His manager wrote on the cover: "Vague but interesting."

It was more than vague. It was revolutionary. But nobody knew it yet.

Three Things: HTTP, HTML, and URLs

Berners-Lee invented three things that remain fundamental to the web today:

HTTP (HyperText Transfer Protocol) is a simple protocol for requesting and serving documents. A client (the browser) sends a request. A server sends back a document. Done. The simplicity was genius—it required minimal resources to implement and could run on any computer.

HTML (HyperText Markup Language) is a markup language for describing documents. It uses tags like <p> for paragraphs and <a> for links. The syntax was borrowed from SGML, an existing markup language, so it had a familiar foundation. But HTML was deliberately simple. You could write a basic web page in minutes. You could view the source of any page and understand it. This openness was crucial—the web didn't require specialized tools or corporate software.

URLs (Uniform Resource Locators) are addresses for documents. They're structured and human-readable: scheme (http), host (example.com), path (/page). A URL tells you both where to go and how to get there. This simple addressing scheme made linking possible and made the web navigable.

The First Website Still Exists

Berners-Lee launched the first web server and first website on December 25, 1990. It was running on a NeXT computer at CERN (he labeled it "This machine is a WWW server. DO NOT POWER DOWN!!" with a sticker).

The first website contained information about the Web itself—what it is, how to use it, how to set up a web server. No graphics. No animations. Just plain text with hyperlinks. It was boring by modern standards. It was revolutionary at the time.

And here's the wild part: the first website is still live at info.cern.ch. CERN preserved it as a historic artifact. You can visit it today, experience the web as Berners-Lee designed it, and see the URLs in their original form. It's a time capsule and a proof of concept: the web is forward-compatible.

Web 1.0: Static, Read-Only, Beautiful in Its Simplicity

From 1990 to roughly 2004, the web was "Web 1.0"—a term that didn't exist until Web 2.0 made it necessary. Web 1.0 was:

• Static: Pages were text files on a server. You wrote HTML, uploaded it, and that's what users saw. No databases, no dynamic content generation, no personalization.
• Read-only: You couldn't comment or interact. You could click links and fill out forms, but mostly you read. The web was a library, not a conversation.
• One-to-many: One company published to many readers. A web page was a broadcast, like a magazine or brochure.
• Minimal design: HTML had no styling language. Sites were black text on grey backgrounds. The aesthetic was utilitarian.
• High barrier to entry: Building a website required learning HTML, having server space, and managing files. It was technical.

Despite these limitations—or maybe because of them—Web 1.0 exploded. The simplicity meant anyone with a computer and internet access could start a website. The cost was low. The learning curve was manageable. By 1995, there were thousands of websites. By 2000, there were millions.

The Browser Wars: Mosaic, Netscape, and Internet Explorer

The first web browser, WorldWideWeb (created by Berners-Lee), was both a browser and an editor. But it was complex and only ran on expensive NeXT machines. The web needed a browser that normal people could use.

In 1993, Marc Andreessen led the creation of Mosaic at the National Center for Supercomputing Applications (NCSA). Mosaic was revolutionary: it rendered images inline, had a graphical interface, and worked on multiple platforms (Unix, Windows, Mac). Mosaic made the web graphical. It made it accessible to non-technical users. It made the web matter.

Andreessen co-founded Netscape Communications and released Netscape Navigator in 1994. Navigator dominated the browser market. By 1995, it had 80% market share. The Netscape IPO in August 1995 was a watershed moment—a company built around an internet browser was worth billions. This IPO triggered the dot-com boom. Suddenly, every investor wanted a piece of internet companies.

But Microsoft saw the threat. Bill Gates reoriented the company around the internet. Microsoft bundled Internet Explorer with Windows, offered it for free, and used aggressive bundling tactics. The "Browser Wars" of 1995-2000 were brutal. Microsoft used market power and monopolistic practices to crush Netscape. By 2000, IE had 95% market share. Netscape was dead. Navigator was sold to AOL.

The lesson: in web technology, first-mover advantage isn't absolute. Deeper pockets and market power matter. But the lesson cuts both ways—open standards survived. HTML and HTTP weren't owned by Netscape or Microsoft. They were open. So the web itself was never captured.

E-Commerce and the Dot-Com Boom

For the first few years, the web was a curiosity. Companies didn't know what to do with it. Then e-commerce proved the web wasn't just for academics and information sharing—it could make money.

Amazon.com launched on July 16, 1994, as an online bookstore. eBay launched on September 4, 1995, as an auction site. These weren't the first commercial websites, but they were the first to demonstrate sustainable, scalable business models. Amazon proved you could sell physical goods online and have them delivered. eBay proved you could create a marketplace where anyone could buy and sell.

These companies required infrastructure: servers, databases, payment processing. Building them was expensive. But the payoff could be enormous. Suddenly, the web wasn't a publishing platform—it was a business medium.

The flood of investment began. Venture capitalists poured billions into internet startups. Companies with no revenue and no path to profitability went public. Stock prices exploded. Every company needed a website. Web developers were in demand and could command high salaries. The web design business boomed.

Between 1995 and 2000, the dot-com boom created a frenzy. Companies like Pets.com, Webvan, and Kozmo.com raised tens of millions to do things that should have been obviously unsustainable. And then, starting in March 2000, it all collapsed. Investors realized many of these companies would never be profitable. Stock prices crashed. Companies folded. But Amazon and eBay survived because they actually made money.

Birth of the Web Timeline

Open Standards Made All of This Possible

Here's what made the web revolutionary: Berners-Lee didn't patent his inventions. He didn't commercialize them. He published HTTP and HTML as open standards. Anyone could implement them. Anyone could build a browser. Anyone could run a web server.

CERN released the world wide web into the public domain on April 30, 1993. There was no licensing. No royalties. No central authority controlling the web. This decision—to open source the entire web—is one of the most consequential decisions in technology history.

Because the web was open, Mosaic could be created at a public university. Netscape could exist. Internet Explorer could exist. Thousands of smaller browsers could exist. No single company controlled the web. No single company could tax the web. This openness created a competitive market in browsers, web servers, and web hosting. Competition drove prices down and innovation up.

Web 1.0 was Just the Beginning

By 2000, the web had been transformed from an academic information-sharing system into the foundation of a global digital economy. But Web 1.0 had severe limitations. Pages were static. Users were passive. Publishing a website required technical skills.

In the early 2000s, new technologies—JavaScript, databases, content management systems—would emerge to make the web dynamic, interactive, and accessible to anyone. These tools would democratize web publishing and eventually create the web we know today: user-generated, real-time, social, and interactive. That's the story of Web 2.0.
