When Tim Berners-Lee wrote a proposal for a distributed hypertext system at CERN in 1989, he could hardly have imagined that this would grow into the dominant publishing platform of modern history. Yet that is exactly what happened. What we retrospectively call Web1 – roughly the period from 1990 to 2004 – marks the phase in which the internet became a public medium.

It is important to immediately dispel one misunderstanding: Web1 is not the same as the internet. The internet had existed decades earlier as a network of networks. Web1 specifically refers to the first phase in the history of the World Wide Web as a layer on that internet, a phase characterized by static pages, limited interaction, and a clear separation between sender and receiver.

This is the story of how that layer emerged, matured, and ultimately laid the foundation for everything that followed.

A Step (Further) Back

To understand Web1, we need to briefly go back to the very beginning. In October 1969, the first host-to-host connection was established via ARPANET between UCLA and the Stanford Research Institute. The first message, 'LO' (the intention was "LOGIN", but the system crashed), is often seen as the symbolic beginning of the internet.

A crucial technical milestone followed on January 1, 1983, when ARPANET officially switched to the TCP/IP protocol. This migration is widely regarded as the moment when the modern internet was born in terms of protocol.

Not long after, in 1983/1984, the Domain Name System (DNS) was specified in RFC 882/883 and later standardized in RFC 1034 and 1035. DNS made it possible to link human-friendly domain names to IP addresses – essential for scalability.

With TCP/IP and DNS, the infrastructure was ready. What was still missing was a universal way to make information accessible and navigable for people. That became the web.

The Invention of the World Wide Web

In March 1989, Tim Berners-Lee submitted his proposal for an information system based on hypertext at CERN. The goal was pragmatic: to enable scientists to collaborate better by linking documents. For this, three building blocks were assembled:

• URL (Uniform Resource Locator) – addressing
• HTTP (HyperText Transfer Protocol) – transport
• HTML (HyperText Markup Language) – document structure

By the end of 1990, the first web server (info.cern.ch, it is still live) was running, and the first browser was developed. In 1991, the web became publicly available.

Architecturally, this was revolutionary due to its minimalism. HTTP was stateless, HTML simple, and the entire system was designed for open distribution. There was no need for a central directory; links were sufficient. A masterstroke; not only because the initial goal was achieved, but also because that goal could be further expanded at the snap of a finger. And that happened.

Mosaic and the Breakthrough to the General Public

The real – or next – breakthrough came in 1993 with NCSA Mosaic, developed at the University of Illinois. Mosaic was not the first browser, but it was the first to be widely distributed and user-friendly. An important innovation was the inline display of images within pages, which greatly increased the appeal of websites.

Mosaic directly led to commercial initiatives. Part of the Mosaic team founded Netscape, which launched the Navigator browser in 1994. Netscape quickly became dominant and set the standard for early web development.

This is where what is now called the 'browser war' began; a battle not only for market share but also for the direction of web standards. Proprietary extensions, incompatible HTML implementations, and JavaScript innovations led to rapid progress but also fragmentation.

Characteristics of Web1

What characterizes Web1 is not the absence of interaction – that existed via email, forms, guestbooks, and newsgroups – but the fact that the web itself was primarily a publishing medium.

Characteristics included:
 

• Static HTML pages
• Server-side scripting via CGI, later PHP and ASP
• Table-based layouts
• Directory structures as a means of navigation
• Portals as gateways (Yahoo, AltaVista)

Search engines played a crucial role. Before algorithmic search dominance, directories (human-curated lists) were leading. Yahoo, for example, started as a manual index of websites.

The web in this phase was primarily a collection of documents. The browser was a viewer, not a runtime environment for complex applications.

Commercialization and the Dotcom Bubble

In the mid-1990s, the web shifted from academic experiment to commercial platform. Companies saw opportunities in e-commerce, online advertising, and digital services. More and more people had a computer at home, and more became possible online.

The hype culminated in the dotcom bubble. On March 10, 2000, the NASDAQ reached a peak of around 5,048 points, after which a dramatic correction followed. Many startups collapsed because business models were lacking. However, the crash was not an end, but a cleansing. Survivors invested in more robust infrastructure, scalable architectures, and real value propositions.

This led to a restart. For IT architecture, this period meant:
 

• Professionalization of hosting
• Rise of data centers
• Growth of LAMP stacks (Linux, Apache, MySQL, PHP)
• Better security practices

Web1 thus became less experimental and more industrial. Will we see another bubble explode this year?

Technical Characteristics of Web1

From a technical perspective, Web1 had several defining properties:

1. Stateless Communication

HTTP was designed as a stateless protocol. Each request stood alone. Sessions had to be implemented via cookies or server-side storage.

2. Server-Centric Logic

Most logic ran on the server. The browser had limited scripting capabilities (JavaScript was only introduced in 1995 by Netscape).

3. Limited Client Capacity

Browsers were relatively simple rendering engines. There was no full-fledged JavaScript runtime as later with Web2.

4. Security in Development

SSL (Secure Sockets Layer) was introduced in the mid-1990s to enable encrypted communication. This made, among other things, e-commerce possible. However, security remained reactive and fragmented.

Consolidation and the Seed of Web2

After the bubble burst, the web did not fall apart – it became more mature. Infrastructure became more scalable and reliable. Broadband internet increased. Web applications became more dynamic.

At the same time, the first platform-like services emerged that would later be labeled as Web2. Wikipedia went live in 2001 (History.com). The idea that users could massively produce and manage content began to gain traction.

Around 2005, the term 'Web 2.0' became popular through O'Reilly Media, implicitly indicating that the first phase – Web1 – was behind us. But that first period was not without purpose.

The Legacy of Web1

Web1 may have been static, but fundamentally transformative. We cannot ignore it; the first years in the history of the World Wide Web laid the foundation for what we know today. The URLs and HTMLs are familiar to anyone with the slightest technical knowledge, and it brought more:
 

• Universal publication without distribution costs
• Open standards as the norm
• The idea of hyperlinking as primary navigation
• A global infrastructure for information

More importantly, Web1 proved that open protocols are scalable. TCP/IP, HTTP, and HTML turned out to be robust enough to still form the backbone of the internet decades later. For IT professionals, that is the most important lesson of Web1: simple, open standards can have exponential impact.

The History of the World Wide Web Starts Here

Web1 was the pioneering phase of the web as a public medium. It began with a hypertext proposal at CERN, grew into a mass platform thanks to Mosaic and Netscape, and survived the dotcom bubble to mature as infrastructure.

It was an era of static pages, server logic, and limited interaction, but also of radical openness and technological simplicity.

The history of the World Wide Web starts here. Without Web1, there is no Web2, no Web3, and no Web4. The foundations laid during this period still form the core of the digital world in which we work.

In 2004, the focus shifted from publishing to participating. Next week, we will dive into Web2; the era of platforms, user-generated content, and the web app as the dominant software form.
