党的根本宗旨是什么？

Mark Zukerberg is the founder and CEO of Facebook, an extremely popular social working website that started in the United States.

Now, millions of student users visit Facebook daily and the website is one of the top ten widely visited sites on the Internet worldwide. College and high school students use Facebook to communicate with friends and share both information and pictures for free. The company earns money through advertising.

Many other companies have been rumored(谣传）to be interested in buying Facebook. Just a few years after Mark started the company, he was approached by Terry Semel, who was the CEO of Yahoo. Terry offered Mark one billion dollars($1,000,000,000) to sell Facebook to Yahoo. Mark said no, though. He stands behind his dreams at the very beginning. He knows the value of the company could fall down; however, he is in this to build something unbelievable, not be bought out by another company.

Maybe he was smart. Now Facebook is rumored to be worth billions of dollars and bigger companies like Microsoft or Google want a share of the company. Some private firms are also interested. Facebook could sell 15billion dollars if Mark decides to sell it at all. Perhaps Mark will just keep working from his California office to continue his dream of building something cool.
