But AOL may infringe

[Animats]

Unlike the Internet, AOL really does have "central computers", located in their big data center in Northern Virginia, and containing all of AOL's "blocks" of proprietary "content", linked by "hyperlinks". So AOL might actually be infringing.

The BT patent comes from a previous generation of technology, which included Ceefax, Prestel, and Minitel. Ceefax and Prestel are dead, but millions of Minitel terminals are still out there; France Telecom uses them instead of phone directories. You can click on the link above and download a Minitel emulator, which allows you to emulate a 16-color block graphics terminal inside a web browser. From there, you can access the telephone directory of France or the Minitel services directory. Most of the services are pay, and at sizable per-minute rates. That sort of fee structure was characteristic of those first-generation systems deployed by telcos.

It's little-known, but Telecom France actually deployed Minitel in the US. There were dial-in ports in all major cities. There were even some English-language services. I had an account for about a year around 1989. International text chat for around $0.06/minute, which was good back then.
