In addition to Satan's response (hell of an answer), I read that if HB had understood residuals from reruns, they might have taken a break-even scenario first run for years of rerun residuals.
I think even 3 full seasons would have been enough. By now of course, it would be sanitized down to 15 minute shows or more likely just cancelled completely, but they could have run this for 20 years or so if they made more.
Exactly. Most shows except maybe for Lucy didn't run consistently in reruns except for the summer. If Paramount had known what a juggernaut Star Trek would turn out to be 5 years after it left the first run air, they very likely would have done at least two more seasons.
