Virginia served as a major center for information technology during the early days of the Internet and network communication. Internet and other communications companies clustered in the Dulles Corridor. By 1993, the Washington area had the largest amount of Internet backbone and the highest concentration of Internet service providers. In 2000, more than half of all Internet traffic flowed along the Dulles Toll Road, and by 2016 70% of the world's internet traffic flowed through Loudoun County. Bill von Meister founded two Virginia companies that played major roles in the commercialization of the Internet: McLean, Virginia based The Source and Control Video Corporation, forerunner of America Online. While short-lived, The Source was one of the first online service providers alongside CompuServe. On hand for the launch of The Source, Isaac Asimov remarked "This is the beginning of the information age." The Source helped pave the way for future online service providers including another Virginia company founded by von Meister, America Online (AOL). AOL became the largest provider of Internet access during the Dial-up era of Internet access. AOL maintained a Virginia headquarters until the then-struggling company moved in 2007.
