Long Live the Web: A Call for Continued Open Standards and Neutrality

The Web is critical not merely to the digital revolution but to our continued prosperity—and even our liberty. Like democracy itself, it needs defending

By Tim Berners-Lee

The principle of universality allows the Web to work no matter what hardware, software, network connection or language you use and to handle information of all types and qualities. This principle guides Web technology design.
Technical standards that are open and royalty-free allow people to create applications without anyone’s permission or having to pay. Patents, and Web services that do not use the common URIs for addresses, limit innovation.
Threats to the Internet, such as companies or governments that interfere with or snoop on Internet traffic, compromise basic human network rights.
Web applications, linked data and other future Web technologies will flourish only if we protect the medium’s basic principles.

The world wide web went live, on my physical desktop in Geneva, Switzerland, in December 1990. It consisted of one Web site and one browser, which happened to be on the same computer. The simple setup demonstrated a profound concept: that any person could share information with anyone else, anywhere. In this spirit, the Web spread quickly from the grassroots up. Today, at its 20th anniversary, the Web is thoroughly integrated into our daily lives. We take it for granted, expecting it to “be there” at any instant, like electricity.

The Web evolved into a powerful, ubiquitous tool because it was built on egalitarian principles and because thousands of individuals, universities and companies have worked, both independently and together as part of the World Wide Web Consortium, to expand its capabilities based on those principles.

The Web as we know it, however, is being threatened in different ways. Some of its most successful inhabitants have begun to chip away at its principles. Large social-networking sites are walling off information posted by their users from the rest of the Web. Wireless Internet providers are being tempted to slow traffic to sites with which they have not made deals. Governments—totalitarian and democratic alike—are monitoring people’s online habits, endangering important human rights.

If we, the Web’s users, allow these and other trends to proceed unchecked, the Web could be broken into fragmented islands. We could lose the freedom to connect with whichever Web sites we want. The ill effects could extend to smartphones and pads, which are also portals to the extensive information that the Web provides.

Why should you care? Because the Web is yours. It is a public resource on which you, your business, your community and your government depend. The Web is also vital to democracy, a communications channel that makes possible a continuous worldwide conversation. The Web is now more critical to free speech than any other medium. It brings principles established in the U.S. Constitution, the British Magna Carta and other important documents into the network age: freedom from being snooped on, filtered, censored and disconnected.

Yet people seem to think the Web is some sort of piece of nature, and if it starts to wither, well, that’s just one of those unfortunate things we can’t help. Not so. We create the Web, by designing computer protocols and software; this process is completely under our control. We choose what properties we want it to have and not have. It is by no means finished (and it’s certainly not dead). If we want to track what government is doing, see what companies are doing, understand the true state of the planet, find a cure for Alzheimer’s disease, not to mention easily share our photos with our friends, we the public, the scientific community and the press must make sure the Web’s principles remain intact—not just to preserve what we have gained but to benefit from the great advances that are still to come.

Universality Is the Foundation
Several principles are key to assuring that the Web becomes ever more valuable. The primary design principle underlying the Web’s usefulness and growth is universality. When you make a link, you can link to anything. That means people must be able to put anything on the Web, no matter what computer they have, software they use or human language they speak and regardless of whether they have a wired or wireless Internet connection. The Web should be usable by people with disabilities. It must work with any form of information, be it a document or a point of data, and information of any quality—from a silly tweet to a scholarly paper. And it should be accessible from any kind of hardware that can connect to the Internet: stationary or mobile, small screen or large.
