The Internet is an immense labyrinth of more than 200 million computers, computer networks, and databases interconnected across the world. Through its user interface, known as the World Wide Web, the Internet gives users access to a vast amount of information, including typewritten text, tabular and graphic material, sound recordings, video images, pictures, and computer programs, which are stored at locations called “Web sites.” Each Web site has a unique address, identified by its alphabetic Universal Resource Locator (URL) and its numeric Internet Protocol (IP). For example, is the URL for Montana State University’s Web server, while is the IP for the school’s Web site. The Internet also enables users to communicate to each other through e-mail, instant messaging, chat rooms, and message boards.

Most users do not access the Internet directly but instead go through an Internet Service Provider (ISP). ISPs typically charge subscribers an hourly or monthly fee for the service they provide. In addition to providing users with a connection to the Internet, many ISPs offer content of their own, ranging from e-mail and video games to personal banking, home shopping, tax, and research services. Subscribers connect to ISPs in a variety of ways, including cable modems and satellite uplinks. However, the most common means of accessing an ISP is over a telephone line. ISPs provide subscribers with telephone numbers that dial into servers that are connected to the Web.

Once connected, users literally have the world at their fingertips. Web sites today are as diverse as they are countless. Governments, governmental watchdogs, non-profit organizations, commercial entities, consumer protection groups, educational institutions, religious institutions, news media, and members of the sports and entertainment industries are just a few of the entities hosting Web sites on the Internet. The group of users visiting these Web sites is similarly large and diverse. In September 2001 researchers estimated that approximately 420 million people were accessing the Internet each day in at least 27 countries. Despite the enormous amount of daily global Internet traffic, no single authority exists to regulate it.

In fact, the Web was designed in part to thwart outside control and withstand foreign attack. The Internet evolved from the Advanced Research Project Agency Network (ARPANET), which was created by the U. S. Department of Defense in 1969 to function as a decentralized, self-maintaining national communications network that permitted computer-to-computer transmissions across vast distances in case the United States came under nuclear attack. ARPANET was programmed to work without human intervention, and sometimes in spite of it. For example, if a communications processing hub became disabled, ARPANET would re-route all transmissions through a different hub.

In the early 1980s the National Science Foundation relied on Internet technology to create the NSF Network (NFSNET), a high-speed communication network that facilitates research at remote academic and governmental institutions. NFSNET now serves as the technological backbone for all Internet communications in the United States. In 1989 English computer scientist Tim Berners-Lee developed the first prototype of the World Wide Web as means for the general populace to access the Internet. A year later he invented the concept of hypertext browsing, a method for imbedding shortcuts into on-screen text, a look that still defines the Internet today. In 1991 the World Wide Web debuted on the Internet, and by 1995 16 million people were reported “surfing” it each day.

As more people posted content on the Web and more people used the Web for personal, governmental, and business purposes, the Internet soon opened the door to an array of lawsuits and legal disputes. In one sense, the legal disputes were as novel as the Internet itself. But in another sense, the disputes merely presented new variations on longstanding legal controversies. As the millennium approached, law schools, lawyers, and judges were recognizing a distinct area of jurisprudence known as Internet law.

Internet law consists of state and federal statutes, case law, and other legal norms that regulate activity on the World Wide Web. Although the law governing the Internet is in many ways no different than the law governing other areas of life in the United States, legal disputes involving the Internet have generally centered on four bodies of law: (1) intellectual property; (2) free speech; (3) privacy; and (4) contracts.
