The World Wide Web (or WWW for short) started in 1990 when a man named Tim Berners-Lee invented it. It is a way for people all over the world to use the internet. With the World Wide Web, people can find information on the internet and share it with each other. They can also create websites, which are like online spaces where people can share their thoughts, ideas, and pictures. The World Wide Web is like a giant library filled with every kind of information imaginable!
