Conrac was a very big name in monitors in the 1970s, including for places like airports with their arrival and departure displays (all black and white at that time, though). I worked on dozens of those monitors into the 1990s. As of less than two years ago, there was still one in San Francisco Airport that has been running 24 hours per day since perhaps 1979, with some capacitors replaced but its original CRT (unless it was replaced before 1984, when I started supporting that monitor).
