I've run into a few cases recently where I've stumbled across shows that have had multiple pilots, a few of which either still didn't sell, or took a long time to get to air. Certainly, there are cases where a producer took a few years between efforts to modify their project, but...
My question is: from a historical standpoint, if a first pilot is followed up by a second in a reasonably short period of time, does this necessarily indicate that a network (or syndicator) was interested in picking up the program (albeit with a few tweaks or set re-designs), or does it more likely indicate that the creator/producer felt so straongly about the concept that they were willing to go to the trouble to shoot a second pilot?
For that matter, who usually pays for this type of second pilot?
As always, any good real-life examples used to illustrate the point would be welcomed!
