Pay attention to the camera & directing the next time you watch an episode, it's an absolute masterpiece.
One example to look out for is the back-and-forth between Columbo and the baddie. They would usually stand in opposite ends of the room and shot from two (sets of) cameras. One camera is closer to Columbo and the other is closer to the baddie, so when the detective is "winning" an argument, he'll look bigger on the screen and vice versa.
This usually starts with a shot where Columbo looks super small somewhere in the back of the room, then he'd ask his famous "just one last question", and then they switch the setup. Now Columbo is bigger in the front, and the baddie looks small while they are in trouble.
