It wouldn't be that hard to fill up a schedule using just the five TV series and 11 feature films. Take a look:
- 11 feature films (3 hours per movie, 33 hours of programming)
- 79 episodes of the original series
- 178 of Next Generation
- 176 of Deep Space Nine
- 172 of Voyager
- 98 of Enterprise (if you must include that horse manure)
And you don't have to air everything in chronological or production order. Think of how many marathons you can do, tying episodes together. Q episodes, Worf episodes, Borg episodes, time travel episodes. 30-40 major cast members amongst the five series, air a block of epsiodes featuring each character they play on their birthdays.
Hey, the jocks have their TV networks. So do musicians, history buffs, kids. You name it, there's at least one channel targetted towards a very specific demographic. And nobody is currently airing DS9 or Voyager, and I barely see TNG on cable these days (a couple episodes on SyFy and BBC America per week). If you build it, they will come. From every quadrant of the Milky Way galaxy, we'll tune in, and we will enjoy it.
