noun : the script and often shooting directions of a story prepared for motion-picture production
Both screenplay and screenwriter date to 1920, though movies themselves are older than that. The first way to watch a motion picture was by your lonesome, via a kinetoscope—a device, invented by Thomas Edison and William Dickson in 1891, that required you to look through a peephole to see teensy moving images inside. The term motion picture dates to 1891 as well.
By the early 20th century, the motion picture industry was ramping up—and changing—and English vocabulary reflected that fact with cinema appearing in print in English in 1909, talkie debuting in 1913, and silver screen in the lexical spotlight by 1918.
