Turbo BASIC

Turbo BASIC is a programming language originally created by Bob Zales and bought from him by Borland. When Borland decided to stop publishing it, Zales bought it back from them, renamed it as PowerBASIC and set up the PowerBASIC company to continue support and development of it. It is still sold today.
