What is a Browser?

Google's Chrome, Microsoft's Internet Explorer, Apple's Safari, and Mozilla's Firefox are examples of popular web browsers.

A web browser (sometimes called an Internet browser) is a software program used to retrieve content on the internet (or the world wide web).  The action of “browsing” allows web users to find and interact with various pieces of online content, including text, pictures, videos, and web pages. 

To understand what a browser is, think about other software programs you use. As much as you need a program to write documents (like Microsoft Word), and a program to work with spreadsheets (such as Microsoft Excel), you also need a program to explore the Web (like Google Chrome or Apple Safari). The program that makes it possible for you to explore the Web is called a web browser.

History of Web Browsers

Many people browsing the internet today may not know Sir Tim Berners-Lee.

Tim Berners-Lee, the inventor of the first web browser
ORLANDO, FLORIDA - JANUARY 18, 2012: Inventor and founder of World Wide Web Sir Tim Berners-Lee delivers an address to IBM Lotusphere 2012 conference on January 18, 2012.

But, in 1989, Berners-Lee invented the protocol (called Hyper-Text Transfer Protocol -- or HTTP) that powers the web. In addition to inventing HTTP, Berners-Lee also invented the first web browser named WorldWideWeb and later renamed Nexus.  He graduated from Oxford University and conducted the work that led to the establishment of the Web while working at the European Organization for Nuclear Research, commonly referred to as CERN (Source).

Today there are several leading web browsers: Chrome, Yandex Browser, Microsoft Edge, Safari, Firefox, Vivaldi, Opera, and SeaMonkey. There are many less-well-known browsers as well.

Since the internet is really just a system to network computers, the history of web browsers can be traced back to the 1960s. At that time, a single computer required a whole room even though a writer for says such computers were "dumber than today's pocket calculators." The same article reports that the first successful networking project (called ARPANET) was a network between the Stanford University Research Institute from a computer science lab at the University of California in 1969 (Source).

For two decades following the transmission of the first message across ARPANET, the internet would remain primarily accessible to formal bodies like the army, private businesses, government agencies, and universities.   

The Web Explosion

Even though Sir Tim Berners Lee's efforts came to light around 1990, the real World Wide Web explosion is considered to have started in 1993. This is the year that computer scientist Marc Andreessen created the first graphical web browser named Mosaic. Andreessen then created Netscape Navigator, which he released to the public in 1994.

The release of Netscape in 1994 sparked a series of browser wars. These battles would eventually lead to the proliferation of web browsers that internet users have come to take for granted today. Microsoft released Internet Explorer in 1995, followed by a series of new versions to deliver better browsing experiences.

Microsoft’s decision to ship its Windows operating system with Internet Explorer pre-installed unsettled the browser market at the time. By 1999, it had gained 99% of the browser market share. But other competitors such as Firefox, Opera, Safari, and Google Chrome emerged in the late 1990s and early 2000s. They began to eat into Internet Explorer’s market share (Source).

What Happened To

Many people using the myriad of browsers today are not particularly technical. Apart from not knowing what a web browser is, they would have no idea whether they are running the latest version of their browser. This is the challenge that the website attempted to solve. was created by Jason Toff, an Associate Product Marketing Manager at Google, in 2009.

The website was available for a short period in December but went completely offline by the end of the same year. There are no reliable reports as to why Google pulled the plug on the website.
