The Kinetoscope, invented by Thomas Edison and William Dickson in 1891, was an early motion picture device that allowed an individual to view short films through a window. The films were composed of 46 frames per second flickering on a film reel illuminated by a single bulb, creating the illusion of moving images. It was finalized in 1892 and unveiled publicly in 1893 at the Brooklyn Institute of Arts and Sciences.

2. What is a Kinetoscope?
The Kinetoscope was designed by Thomas Edison and William Dickson in
1891. It was designed for an individual to view the film at one time,
through a window or scopes in the top of the machine.
The video inside the machine is made up of a series of images on a film
reel flicking through, 46 frames per second with a single bulb to
illuminate and to give the illusion that the images are moving.

3.  In 1892, the Kinetoscope was finalised with a minor change of the
film running process, it was replaced from a horizontal spool to a
vertical spool.
 It was unveiled and introduced to the public at the Brooklyn institute
of arts and sciences in 1893.
 The reason for the small scope to see the images is due to the light, if
too much light is introduced to the film reel, the picture will become
less clear and harder to see, the darkness and the single bulb ensure
that the images are as clear as possible.
