Fictional Fans

If I'd had anyone to talk to about it, I probably would have gone on endlessly about how dreamy Spock was. *g*

A few years later I used to race home from school, watch Dark Shadows and then get on the phone with my best friend to dissect the episodes and talk about how dreamy Barnabas/Quentin/et al. were.

But if you're taking fandom to specifically mean written fanworks and meta, then yea, 1977 and Star Wars.
