It's kind of odd for me, an American, to think that colo(u)r TV didn't come in Australia until 1975... although I can understand it from a technical standpoint, it's just that I'm used to thinking of TV shows, and game shows especially, from the period of about 1968 to the late 70s as overemphasizing the color and being louder and more extravagant because of the introduction of color, as compared to the quieter, more drab, and more conservative feel of programs from the black-and-white era, and I have a hard time trying to envision that black-and-white feel continuing all the way into 1975 somewhere else... if you know what I mean. </rant>
EDIT to avoid adding another post: Odd how they used the shrunken dollar sign -- which I just now realized that they must have based off of the American logo, which was, at the time, still "new". Also, on another tangent, it seems rather sparsely lit. I can't even see the host's face when he's walking through the door. Am I seeing things right?
