What is "hyperland"

Hyperland is a 50-minute long documentary film about hypertext and surrounding technologies. It was written by Douglas Adams and produced and directed by Max Whitby for BBC Two in 1990. It stars Douglas Adams as a computer user and Tom Baker, with whom Adams had already worked on Doctor Who, as a personification of a software agent.

In hindsight, what Hyperland describes and predicts is an approximation of today's World Wide Web.
