Jason Kottke mentioned this post about the economics of pinball, which brings up questions about more than just what our all-time high scores were:

Black Knight brought pinball to a new level, literally speaking because it was among the first games with ramps and elevated flippers, but even more importantly because it brought a new challenge that drew in and solidified a pinball crowd. In doing so it also set the pinball market on a path that would eventually lead to its demise.
