The Scopitone was a early music video jukebox invented in France, that played a short music video clip after you threw in a coin. It was mostly placed in bars, and was apparently a big thing in Europe after the second world war.
As apparently most videos were produces by a rather small number of producers and had to lure the audience into paying for the material, many of the videos have a somewhat similar style: The things targeted an adult audience, and many of the videos that were available were - at least by the standards back then - a bit smutty, and usually feature lightly-clad, over-the-top merry female dancers.
The whole business had close ties to the mob, and - according to my information - went into decline over a mafia-intern conflict (Wikipedia, however, states that American and British acts boycotted the thing due to its bad reputation, others state that color-TV was responsible for their decline).
Many Scopitone videos can be watched on Youtube. They are a interesting time-capsule for the everyday-culture back then, and many of the material is so outdated that it appears nearly like a parody from modern perspective:
