Good luck! I hope you get sponsorship!
If you can't get a corporate sponsor, I think you should go all Kevin Smith or College University and just burn your own DVDs and sell them online. Aniboom is another possibility... but of course, it depends on how hard it is for you to produce this stuff. If it took you 2 years to produce that 1 minute demo, then yeah, you'll need corporate sponsorship for a render farm or more manpower or whatever else you need... even just the cost of living for a few years!
You don't see a bunch of cute cartoons on TV that cover advanced topics like the meaning of life and the implications of sentient artifical intelligence. That's why I don't immagine you'll attract corporate sponsorship. Don't get me wrong, I hope you do get paid! But since it's SUCH a long-shot for any show that's actually got worthwhile content, you should definitely be exploring other payment models.
Best of luck to you! This was a VERY intriguing demo!
