Here's a clip that I don't remember seeing. It's Dallas station breaking into the program live as the assassination happened. It goes on into an interview with Zapruder, who captured the assassination on his 8 mm film. He never kept a copy of the film he took.
On a lighter note, look how different broadcasts were then? Old fashioned telephones, smoking at the desk...just bare necessities, nothing high tech.
