What is the history of Delphi?

Delphi is the descendant of Turbo Pascal, which was first released in 1983 for the CP/M operating system. Turbo Pascal was ported to MS-DOS in early 1984. During the early history of the IBM PC, Turbo Pascal was arguably the most popular language for serious development work--mostly because it was a real compiler, including the program editor and everything, that cost $19.95 and would run on a 128k machine. Borland introduced Turbo Pascal for Windows in 1990. The latest release of Borland Pascal (as it is now called), not including Delphi, was version 7.0 in late 1992.
