Actually, for most of these other shows you mention, they now hire consultants to make the display as accurate as possible (within the limits of dramaturgy requirements, nobody wants to see a cop fill out reports or show docs hook up the 100th dialysis patient).
Just, oddly, for "computer movies" you never get to see an expert on the team. Why? Because, let's face it, our work is just plain BORING to watch. From programming to administration, hell, even hacking is boring to watch. Mostly because to find it entertaining, you already have to know a fair lot of the stuff to even understand what's going on. Everyone can understand why cops chase a robber and how a shootout works. Everyone can understand why the operation room gets hectic when you hear the flatline beep. But computers? Even if it gets hectic for us, it's hard to convey just why. It's never life or death, no matter what we do. Nobody's going to die if the server isn't up in a minute. And there's preciously little we could do to speed it up or some clever trick we could pull when we wait for a server to come online.
It's just not interesting to watch real computer stuff.
