In my daily routine of scouring the web for interesting and nerdy things, I stumbled across perhaps my new favorite infographic (replacing this one).
It’s called The History of Science Fiction and it covers everything you could ever think of in the science fiction genre, tracing literary and cinematic roots from Firefly and Battlestar Galactica all the way back to ancient legends and mythology. The graphic was created by Ward Shelley, who apparently was surprised when it leaked onto the Internet and got gobbled up by geeks. He embraces the exposure, but makes sure to note that he is selling posters (and I just might pick one up).
Enjoy the graphic. You could spend hours scouring it for the next thing to read or watch, or simply search it for the history of your favorite nerdy excursions.
