"One of the early nicknames for the Internet was the "information superhighway" because it was supposed to provide the average person with fast access to a practically limitless amount of data. For many users, that’s exactly what accessing the Internet is like. For others, it’s as if the information superhighway has some major roadblocks in the form of Internet censorship.
The motivations for censorship range from well-intentioned desires to protect children from unsuitable content to authoritarian attempts to control a nation’s access to information. No matter what the censors’ reasons are, the end result is the same: They block access to the Web pages they identify as undesirable." – Content courtesy of Howstuffworks “How Internet Censorship Works”
