On this date in 1887, Thomas Edison received the patent for his Kinetoscope, the precursor to modern projection film. Early versions were used by a single person who viewed the film through a window on the top of the device. The Kinetoscope worked essentially the same way as modern film. Sequential images are shown at high speed over light to create the illusion of movement.
As time went on, improvements to the design created the ability to add sound and earphones to the films using a phonograph. Later, it was also able to project film, in a manner not much different than we use today.
The first copyright for an identifiable motion picture was given to Thomas Edison for "Fred Ott's Sneeze," which, predictably, depicts a Fred Ott's sneeze.
I don't know about you guys, but I always think it's interesting to look back and see what kind of 100 year old technology we still use today. We make leaps and bounds in areas, but film doesn't change much, neither have radios. Any other kind pieces of technology that haven't changed a whole lot over the years? Things we still use?
