I don’t remember AI being used as a widespread marketing term until 2-3 years ago. Before that it was just more of a vague tech thing you’d sometimes see, but now every single app seems to have reframed their business to be about AI agents.
There have been at least 3 waves of AI before the LLM generation. 70s , 80s and late 90s.

Early 2010s had a lot of neural networks AI stuff going on and it certainly became a minor hype cycle as well though that kind of resulted in the current LLM wave.
