Probably because vendors with deep financial pockets specifically designed/developed/selected these languages (JavaScript, Java, ...) to become popular, integrated them into their offerings and invested billions into it?

Lisp was already at the end of its hype cycle and had entered the death zone (-> the AI winter end 80s), when the Internet took off start/mid 90s. L*** was a forbidden word in the 90s.
