Sometime at the end of the 80's, when I was still an innocent adolescent, I made my first contact with video on demand in a hotel room. There was a box under the TV set, with which you could choose from a couple of movies. The first five minutes were free, then you were charged for watching the movie (luckily, I managed to hold myself back from watching more than the free five minutes of "Amanda at Night", or howsoever that masterpiece was called).
Is there a word for this particular kind of box? My Google search was unsuccesful.
