Case decided the company needed a new image, so he held a contest for a new name. He picked himself as the winner and America Online was born, although it's first name was Online America. In 1992, with just 120 employees, AOL went public, raised $66 million and Case was suddenly worth nearly $2 million on paper. Shortly after that, he was made CEO.
