Web browser: the story on HearLore | HearLore
Web browser
In 1990, Sir Tim Berners-Lee created the very first web browser, a program he simply named WorldWideWeb, without realizing he was about to build the infrastructure for the modern global economy. This initial software was not merely a tool for reading text; it was a dual-purpose editor and viewer that allowed users to create and modify pages directly within the interface. Berners-Lee, working at CERN in Switzerland, designed this system to help scientists share data, yet the implications of his invention rippled far beyond the laboratory. He did not patent the technology, instead releasing it to the public domain to ensure that the web would remain an open platform for everyone. This decision to keep the core technology free became the foundation upon which billions of dollars of commerce and communication would be built over the next three decades. The browser was the key that unlocked the potential of the internet, transforming it from a niche academic network into a universal library of human knowledge.
The Graphical Revolution
The true explosion of the World Wide Web did not occur until April 1993, when the Mosaic web browser was released to the public. Before Mosaic, the internet was largely text-based and difficult for the average person to navigate, but this new software introduced a graphical user interface that allowed images and text to coexist on the same page. Mosaic was the first browser to find mainstream popularity because it made the web easy to navigate and visually engaging for the average person. The lead developers of Mosaic, including Marc Andreessen and Eric Bina, were students at the University of Illinois who saw the potential for a commercial future. They left the university to found the Netscape corporation, which released the Mosaic-influenced Netscape Navigator in 1994. Navigator quickly became the most popular browser, sparking the Internet boom of the 1990s when the web grew at a very rapid rate. This era marked the transition from a tool for academics to a medium for mass communication, setting the stage for the fierce commercial battles that would follow.
The Browser Wars
Microsoft debuted Internet Explorer in 1995, leading to a browser war that would define the technology landscape for the next decade. Within a few years, Microsoft gained a dominant position in the browser market for two reasons: it bundled Internet Explorer with its popular Windows operating system and did so as freeware with no restrictions on usage. The market share of Internet Explorer peaked at over 95% in the early 2000s, effectively creating a monopoly that stifled innovation and competition. In 1998, Netscape launched what would become the Mozilla Foundation to create a new browser using the open-source software model, a direct response to the corporate dominance of Microsoft. This work evolved into the Firefox browser, first released by Mozilla in 2004, which saw its market share peak at 32% in 2010. The war ended not with a treaty, but with the obsolescence of the victor, as Microsoft eventually replaced Internet Explorer with Edge in 2015 and then again with a Chromium-based version in 2020.

The market share of Internet Explorer peaked at over 95% in the early 2000s. Microsoft gained this dominant position by bundling Internet Explorer with its popular Windows operating system as freeware with no restrictions on usage.
When did mobile devices represent the majority of web traffic?
Mobile devices have represented the majority of web traffic since late 2016. As of February 2025, mobile devices represent a 62% share of Internet traffic, followed by desktop at 36% and tablet at 2%.
Which browsers are considered privacy-focused according to a 2020 study?
A study from 2020 identifies Brave, DuckDuckGo, and Firefox-Focus as privacy-focused browsers that perform better than popular ones like Chrome, Firefox, and Safari. These browsers block fingerprinting, cookies, tracking scripts, ads, and other invasive technologies to protect user anonymity.
When did AI browsers start becoming increasingly common in the mid-2020s?
Starting in the mid-2020s, browsers with integrated artificial intelligence capabilities known as AI browsers have become increasingly common. Examples include Perplexity Comet, ChatGPT Atlas, Chrome with the Gemini chatbot, and Edge with the Copilot chatbot.
Behind the colorful interface of every browser lies a complex engine responsible for converting downloaded resources into an interactive visual representation of the page. This process begins when a user inputs a Uniform Resource Locator, such as https://www.wikipedia.org, into the browser's address bar. Virtually all URLs on the web start with either http: or https:, which means they are retrieved with the Hypertext Transfer Protocol. For secure mode, the connection between the browser and web server is encrypted, providing a secure and private data transfer. The browser's engine, also known as a layout engine or rendering engine, is responsible for converting those resources into an interactive visual representation of the page on the user's device. Modern web browsers also contain separate JavaScript engines which enable more complex interactive applications inside the browser. A web browser that does not render a graphical user interface is known as a headless browser, often used by automated scripts to test websites or scrape data.
The Mobile Shift
Prior to late 2016, the majority of web traffic came from desktop computers, but since then, mobile devices have represented the majority of web traffic. As of February 2025, mobile devices represent a 62% share of Internet traffic, followed by desktop at 36% and tablet at 2%. This shift forced browsers to evolve from desktop-centric tools into compact applications designed for touch screens and limited processing power. Mobile browsers have similar UI features as desktop versions, but the limitations of the often-smaller touch screens require mobile UIs to be simpler. The difference is significant for users accustomed to keyboard shortcuts, leading to the development of responsive web design to create websites that offer a consistent experience across the desktop and mobile versions of the website and across varying screen sizes. The most popular desktop browsers also have sophisticated web development tools, but the mobile experience prioritizes speed and simplicity over the complex customization options found on larger screens.
The Privacy Paradox
During the course of browsing, cookies received from various websites are stored by the browser, creating a detailed profile of user behavior over long periods of time. Some of them contain login credentials or site preferences, while others are used for tracking user behavior, so browsers typically provide a section in the menu for deleting cookies. A study from 2020 portrays that there are two tiers of browsers in terms of privacy: the privacy-focused ones like Brave, DuckDuckGo, and Firefox-Focus perform better than popular ones like Chrome, Firefox, and Safari. Blocking fingerprinting, cookies, tracking scripts, ads, and other invasive technologies seems to explain that difference. Telemetry data is collected by most popular web browsers, which can usually be opted out of by the user, yet the default settings often favor data collection. This tension between convenience and privacy has led to the rise of specialized browsers that prioritize user anonymity, even if it means sacrificing some features or compatibility with certain websites.
The AI Frontier
Starting in the mid-2020s, browsers with integrated artificial intelligence capabilities, known as AI browsers, have become increasingly common. This includes both new entrants to the browser market, such as Perplexity Comet and ChatGPT Atlas, and established browsers that added AI features, such as Chrome with the Gemini chatbot and Edge with the Copilot chatbot. These new tools are transforming the browser from a passive window into the web into an active participant in the user's digital life. The integration of AI allows browsers to summarize long articles, generate code, and answer complex questions directly within the interface. This evolution marks a significant shift in how humans interact with the internet, moving from a model of manual navigation to one of conversational assistance. As these technologies mature, the browser may become less of a tool for finding information and more of a platform for generating it.
