Similarities and differences to the World Wide Web

Through its influence on Robert Cailliau (who assisted in the development of Tim Berners-Lee's first Web browser), Hypercard influenced the development of the Web in late 1990. - wikipedia

Although Hypercard stacks did not operate over the Internet, by 1988 there were at least 300 stacks publicly available for download from the commercial CompuServe network (which was not connected to the official Internet yet) and the system could link phone numbers on a person's computer together and enable them to dial numbers without a modem.

In this sense, like the Web it did form a "brain-like" association/link-based experience of information browsing despite the fact it didn't operate remotely over the TCP/IP protocol at that time. Like the Web, it also allowed for the connections of many different kinds of media.
