Anime sure has come a long way since 1917. The 15 minute video below from The Association of Japanese Animations (AJA) goes all the way back to the days of clay, stop-motion puppets to the present time of shonen battle series and magical girls [It seems licensing issues kept any Studio Ghibli works from being featured].
The AJA isn't done celebrating anime's centennial celebration. A special five hour program will air on the NHK during New Year's Eve which focuses on how voice acting has evolved over the last 100 years.
Take a look at the video below to gain a sense of just how muh anime existed before you joined the fandom or if you're a longtime viewer, prepare your nostalgia-feels for a trip down memory lane.
