The internet became popular through the internet service called "world wide web" which was invented in 1989. The "web" is primarily made of websites which are accessible with programs called "web browsers" (eg Netscape Navigator or Microsoft Internet Explorer). However, there are also much older internet services (eg e-mail and usenet) and newer ones (eg WAP) for which you need different programs.
