Man, I used to love me some Buck Rogers In The 25th Century when I was a kid, and not just because I had a serious crush on co-star Erin Gray! The sci-fi was just far out enough to hold your attention without making you learn an encyclopaedic amount of factoids, and the fashion was dy-no-mite!
All kidding aside, as a kid growing up in the 80s Buck Rogers and Battlestar Galactica fed my geeky addiction to sci-fi like no other show could, and kept me firmly planted in front of the television, my mind racing at the possibilities presented in each episode.
Head to the link to find a bunch of sci-fi elements Buck Rogers predicted would become a part of mankind's future. They're hilarious and mostly outdated, although if any of them do come true the future will be a scary place indeed!
