when he was in his second year at Harvard,Mark started to create programs of students.
He wrote a program called CourseMatch, which allowed users to choose classes based on the popular choices of other students. He also started Facemash, which allowed users to compare two student photos and decide who was more attractive. The program became very popular, but the school administration shut it down, because they thought it was hot good thing to do.
