The Internet got its start in the United States more than 50 years ago as a government weapon in the Cold War. For years, scientists and researchers used it to communicate and share data and files from one computer to another. Today, the Internet change. And we use the Internet for almost everything. For example, we need internet to book flights, transfer funds from the bank account, check bus timetables, send email, search Google, make call by skype, buy or sell stuff on eBay, washes video on YouTube, chat with friends. For many people it would be impossible to imagine life without internet. That is why an Internet change from a simply way to send files from one place to another for itself a “web” of information that anyone on the Internet could retrieve. Over the past two decades, the exponential growth of the Internet has led it to touch upon every aspect of modern life in the world.
Who controls the World Wide Web? The TCP protocol on which all Internet protocols are based is not patented and can be implemented by anyone. It can also continue to operate without any one central system in charge. Although no single person or organization controls the Internet, NSI’s brief experiment with redirecting all mistyped domain names to their own ads demonstrated that they do hold a great deal of practical power. This does not mean that they can do whatever they like, of course; political pressure and the threat of lawsuits led them to stop their ad-redirection policy, at least for now.
Internationally speaking, there is truly no one entity in charge, as each national domain has its own registrars for example .fr for France, .uk for United Kingdom. Certainly the global physical network itself does not belong to any one company.
In some way, Google has control, because it is the most popular search engine, and for a period of time several other competing search engines actually relied on Google for their results. However, Yahoo has stopped using Google in this way, and Microsoft has announced its intention to compete seriously with Google.
Unfortunately, in some countries, effective Internet censorship does exist. Web access in China is severely filtered for political content.
