What do dogs like to watch on TV? Video games?

My dog has figured out that the xbox controller controls the TV and he is fascinated. He seems to be more interested in video games than other things on television. Does anyone know what dogs like to watch? Just curious, the TV is not going to turn him into a couch potato any time soon, heh.

Wiki says, "Like most mammals, dogs are dichromats and have color vision equivalent to red-green color blindness in humans (deuteranopia). Dogs are less sensitive to differences in grey shades than humans and also can detect brightness at about half the accuracy of humans."
