..there were toys and videos games to made from Trek now, Paramount wasn't going to loose out on that momentum. Not with Star Trek: the Experance waiting to launch and a new network to compete with FOX and/or the WB. Trek was bigger then than it ever was. During that time, waiting just wasn't an option.
But even Star Wars knew better than to try and make TV shows at the same time they were making the Prequel movies, or try and make a TV show while they were making the OT.
With all that stuff, like the Experience and everything, did it occur to them that over saturation would end up halting the momentum anyways?
One of the difference is, Star Wars is all readt reaching the audience Paramount wanted Trek too. Lucas & FOX have liitle worries that SW won't reach out to the new/next generation of fan. ST can often to stiff for many, which it why it has a harder time reacting the next wave of fan.
Why would they, TNG and it's film did very well. While DS9's viewership faltered next to TNG's, it still held strong for a show first run in syndication. There was very little at the time that showed signs of such trouble. I'm sure it was a concern but not one they thought they couldn't get out of. Voyager is still a success story, it endured to spite all that was set against it.
However, over saturation wasn't the only issue.
Local networks in major citys showed Voyager at the same time as DS9.
Some cities didn't show Voyager at all.
I live in the NYC area, which is considered one of the huge entertainment hubs.
It's also the most densely populated areas in the US.
NYC was one of those cities where Voyager was shown up against DS9.
How many Neilson households are in this area alone?
How many of them were Trek viewers?
How many of the viewing audience were divided upon which one to watch that night?
How does that effect the status of a show?
That's another factor.
Did Voyager disappoint due to stories or is a major part due to network scheduling?
During sweeps weeks, who got the bigger budget due to higher viewer turn out?
