As a side question: I know TNG and DS9 were produced in syndication, but what about the other series?
Here goes:
Roddenberry first pitched the idea of Star Trek to CBS way back in 1964 or so. They turned it down in favor of
Lost in Space. He then took it to NBC. The original pilot, "The Cage", impressed the execs at NBC, but they were basically too stupid to understand it ("too cerebral" were their own words), and so asked for a second pilot. The second pilot introduced Kirk as the captain, and the NBC execs had an easier time understanding it, since it ended with Kirk in a fist fight.
However, NBC repeatedly dumped the show in unfavorable time slots, and it was always threatened with cancellation. It managed to survive three seasons because of huge fan support, but at the end of the third season they pulled the plug. Of course, if they didn't make the brain dead decision of putting it on 10 pm on Friday night, it might have done better, but who knows? After cancellation,
Star Trek entered syndication, where it gained a great deal of popularity.
An animated Trek series was aired during the early 70s, but I know little about it, and it's not considered to be canonical (for the most part) anyway.
In the late 70's Paramont tried to start up a fourth television network, but plans for that ultrimatly fell through. A new Star Trek show was to be one of the series offered on the network, and sets were built, scripts were written, and so on. After the success of Star Wars, they decided to do a featrue film instead, and some of the scripts for this series were rewritten for TNG.
TNG was created during the mid 80's and launched in 1987. Roddenberry decided to put it directly into syndication, probably because of the bad history Trek had had with networks and/or the fact that Star Trek had done better in syndication than on the networks. DS9 was also produced in syndication later.
Star Trek returned to the netwroks with Voyager. In the early 90s, Paramont succeeded in establishing a TV network, and Voyager was the first show that aired on UPN. Later, Enterprise was also produced for UPN.
