I don't know exactly what kindled my interest in SciFi, but I think it most likely was Star Trek (TOS) in the 80s. Caught a bit of the Next Gen when it aired in the 90s, but due to work, I had not much time to watch TV. Though, a few years later, after the company I woked at went bancrupt, I had more than enough time and caught some reruns of ST:TNG during sleepless nights. The stories that were the most fascinating for me were those that dealt with temporal paradoxons or the multiverse idea. Caught a bit of B5, and I think some Battlestar Galactica, but all this ran at times that were awkward for me to be able to watch. And those night time reruns weren't optimal, either, as I would regularly fall asleep while watching.
In terms of books, there wasn't much happening back then, as I had to cope with little funding for anything, so if I would buy a book, I wouldn't do much experimenting and stick to the stuff I knew I liked. It took up into my mid-teens that I started looking around, thanks to classmates. One thing that was quite popular, back then, was Steven King. Got a handful of his books, over time, but I don't think I read any of them more than twice. Christine made me feel uneasy when I had to go home on foot on a very foggy evening, and Pet Cemetary came back to haunt me last year when our cat was murdered. Aside from these, there is a copy of the "Werewolf of Barker Mills" script, a collection of short stories and "The Stand". But I have to admit that Horror isn't my cup of tea. And SciFi... Well. Although this was a topic that really intrigued me, alongside fantasy, I still had that issue with too much month left at the end of the money and real estate for building an extensive library was equally scarce. Maybe nowadays, where all you need is an internet connection and some storage, I might be able to take a look around.
