I think pinball really reached its peak popularity in the late 1970's and 1980's but most of the best pins came out in the 1990's. I remember going to arcades and there was mostly pinball machines and over a few years time it became mostly video arcade machines, and the generation after me slowly lost interest in playing pinball. i would go in an arcade 20-25 years ago and it was all video, there might be a couple of pins that would be mostly unplayable.
