I was working for a major network broadcaster during the Y2K period. Let me tell you, if we hadn’t done anything to correct the problems, it could have crippled our Corp. We examined every single electronic box in our entire system and replaced hundreds of “faulty” components from studio to mobile to transmitter to satellite to cable. It was a massive and expensive replacement project. At the end of it, when the ball fell in Times Square....NOTHING happened to us. But it took big bucks, two years, and the hard work of hundreds of people to say that.
Sounds like you made good bucks during that “emergency refit”.
