Good BBC article describing the impact of HyperCard, pre-Web software from Apple released in 1987. It enabled you to create hypertext “cards,” that in many ways anticipated what websites would become several years later. I remember using HyperCard on the Apple Macintosh computers at Victoria University of Wellington, in my first year there in 1990. From the BBC article:
Bill Atkinson, its developer, described HyperCard as “an erector set for building applications.” Simply put, you could build your own software using HyperCard, with each program made up of “stacks” of “cards”. Each card could contain text and images, as well as interactive elements like buttons, with the ability to interconnect between other cards. Think of these stacks as rudimentary websites of sorts that exist entirely on a single machine, with each card as a page.
