| There were tons of alternative hypertext systems before the world wide web. Major reasons WWW succeeded: 1) Open standard, no license required. (My understanding is that TB-L worked hard to make this happen.) 2) A forgiving text-based format that was trivial to author, serve, and display. And evolve with forward/backwards compatibility. 3) One-way links. (Many other HyperText projects were hung up on bi-directional links.) 4) URLs didn't require any centralized authority other than already-existing DNS. |
