Fred Rogers did something that the producers of DTN haven&#x27;t; he drew strict boundary lines between realism and make-believe, opening each Neighborhood of Make Believe segment with &quot;Let&#x27;s pretend...&quot; This emphasis on exposing fiction as <i>not real</i> tightened as the show went on: Picture-Picture would eventually lose its &quot;magical&quot; properties, and in one episode Fred actually walked off set and introduced the kids to the cameramen, boom operators, and so forth.
