World without live television

[True Federalist (진정한 연방 주의자)]

One of the principle components of the television system is the camera.  Suppose that no practical camera for live television is developed.  (The image disector works at very bright light levels and thus can be used to televise film even if live broadcast is impractical.)

Obvious changes:
No television guided missiles for the military.
Spot news coverage with live video uplinks is impossible.
Same for live sports coverage.  (Film delay of perhaps as little as 15 minutes is doable, but would it be worthwhile enough in such cases to cause rush film development to be regularly done?)

Clearly, radio remains a major medium for broadcast news and sports, since it can offer live coverage that television can't.
Does broadcast facsimile ever advance past the experiment stage and become a major medium as people thought it might in the 30's and 40's?
How does the 21st century even function with the videocam cellphone?

Does the change in how war is covered affect Vietnam and later conflicts?
Of course that assumes that President Nixon would have gotten us into Vietnam in the 1960s.  People who listened to the Nixon-Kennedy debate thought Nixon won the debate and even if televised, the debates could not have been shown live and thus would have been seen by far fewer voters.
