When Mark Cuban purchased the Dallas Mavericks on January 14, 2000, the face of the organization began to change immediately. Once again Mavericks games had a party atmosphere as Reunion Arena rocked with the return of the "Reunion Rowdies."... Cuban co-founded HDNet, an all high-definition television network on DIRECTV channel 199 which launched in September 2001. Prior to his purchase of the Mavericks, Cuban co-founded Broadcast.com, the leading provider of multimedia and streaming on the Internet, in 1995, selling it to Yahoo! in July of 1999. Before Broadcast.com, Cuban co-founded MicroSolutions, a leading National Systems Integrator, in 1983, and later sold it to CompuServe. Today, in addition to his ownership of the Mavericks, Cuban is an active investor in leading and cutting-edge technologies and continues to be a sought-after speaker.
