HyperCard

HyperCard was an application program and programming tool for Apple Macintosh and Apple IIGS computers that was among the first successful hypermedia systems before the World Wide Web. It combines database capabilities with a graphical, flexible, user-modifiable interface. HyperCard also features HyperTalk, a programming language for manipulating data and the user interface.

This combination of features - simple form layout, database capabilities and ease of programming - led to widespread use in many different roles. Some HyperCard users employed it as a programming system for Rapid Application Development of applications and databases, others for building 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 at the time. It was withdrawn from sale in March 2004, although by then it had not been updated for many years.
