Mark Zuckerberg was born on May 14, 1984. As a little kid, he loved creating little fun computer programs, especially communication tools and games.

When he was a student at Harvard University, Mark founded (创建）Facebook on February 4, 2004. Through Facebook, Harvard students could communicate with each other. Facebook quickly became a great success at Harvard and more than two-thirds of the school’s students used it in the first two weeks. It soon spread further to any university students, then high school students, and, finally, to anyone aged 13 and over in the US. 

Facebook developed fast and became popular. People can communicate with others, add friends, and send them messages. Now, it has more than 175 million users all over the world.

Many big companies have offered a very high price to buy Facebook, but Mark refused them all. His reason was simple. “We are not planning to sell it. We don’t want to make money from it. We just hope Facebook will make it easier for people to know each other.”

Sometimes the simplest ideas go the furthest. We hope Mark can go much further, maybe even further than Bill Gates!
