Bill Atkinson's HyperCard shipped bundled free with every Macintosh, letting users create stacks of linked, clickable cards containing text, images, and simple scripts. Its intuitive HyperTalk scripting language and card-and-stack metaphor influenced a generation of programmers and is widely credited as a conceptual precursor to the World Wide Web's hyperlinked structure.
Bill Atkinson, already famous for creating MacPaint and QuickDraw, conceived HyperCard partly under the influence of an LSD experience that he said gave him a vision of connecting pieces of information nonlinearly, like connected note cards on a corkboard. Apple's Steve Jobs was skeptical of a tool that empowered non-programmers, but Atkinson persisted.
HyperCard let anyone — not just professional coders — build interactive applications by linking "cards" together with clickable buttons, using a simple scripting language called HyperTalk that read almost like plain English. Amateur developers built everything from choose-your-own-adventure games to corporate training tools to early hypertext encyclopedias.
Tim Berners-Lee later acknowledged HyperCard's stack-and-link structure as an influence on his thinking about the web, though HyperCard's links stayed confined to a single machine while his creation spanned the globe. Apple discontinued HyperCard in 2004, but its DNA lives on in the very idea of clickable, linked digital documents that underpins the modern internet.
