Following Google, MySpace and Facebook's Website Creator becoming rich by Internet creativity, social networking myYearbook also made Cook, a 18 year old girl from New Jersey in the United States, enter the ranks of rich women.

According to Hongkong's Wen Wei Po, Cook, when he was just 15 years old, went to high school one day. He looked at the Yearbook with his brother, and found a friend of two people. But the photo was obviously old enough to keep up with the face of the friend. So the idea of putting the annual issue online was raised. MyYearbook was born in 05.

Cook invested $250 thousand in that year. Now the website has become the third largest social network in the United States after MySpace and Facebook, bringing her $10 million advertising revenue a year, making her a billionaire in just 3 years.
