Whne I was a kid it was cowboys ,indians and soldiers killing each other. Of course the effect wasn't the same on black and white tv and theatre.
Same when I was a kid except with the addition of both WWI pilots (on bicycles) and Civil War (Yankees and Confederates).
I never saw American TV until I was seven and within 6 weeks of graduating 1st Grade. I never saw a color tv until my parents took me to their friends house a couple years later. I don't recall when we first owned a color TV, but I do recall that I watched first Star Trek episodes well into the first season in B&W (1967) and don't recall a color episode until 1968.
