The Price is Right

So i watched an old episode of The Prince is Right. It said it was the first episode and it aired on 09/04/72. As i watched the episode i felt like the camera guy focused more on the actual items then the models, unlike later shows where they always have a camera on the model. As far as their movements i felt like nothing much has changed because they are always showing off the item with the same movements but i don think that they were as forced back then as they are now. Forced as in 'look at these prize but really look at me' that's what i get from the new models but the old models their movements were light and casual.
