HyperCard combines a flat-file database with a graphical, flexible, user-modifiable interface. HyperCard includes a built-in programming language called HyperTalk for manipulating data and the user interface. This combination of features - a database with simple form layout, flexible support for graphics, and ease of programming - suits HyperCard for many different projects such as rapid application development of applications and databases, interactive applications with no database requirements, command and control systems, and many examples in the demoscene.
HyperCard was originally released in 1987 for $49.95 and was included for free with all new Macs sold then. It was withdrawn from sale in March 2004, having received its final update in 1998 upon the return of Steve Jobs to Apple. HyperCard runs in the Classic Environment, but was not ported to Mac OS X.
