The internet is the world-wide communication network of computers. It has millions of smaller domestic, academic, business, and government networks, which together carry many different kinds of information. The Internet was developed in the United States and was first connected in October 1969. It is used for many things, such as electronic mail, online chat, file transfer and other documents of the World Wide Web (which is also called the "Web"). The Web was created in Switzerland in 1990 by a British scientist, and it is used by billions of people all over the world. The web contains websites, including blogs. Webpages on the Internet can be seen and read by anyone (unless the page needs a password, or it is blocked). The second biggest use of the Internet is to send and receive e-mail. Today, people can pay money to access the Internet from internet service providers. Some services on the Internet cost nothing to use. Sometimes people who offer these free services use advertising to make money.
