Recently I got a hold of a copy of The ultimate Encyclopedia of fantasy and it was a fun read, with reviews and points of view regarding fantasy movies, books, and TV.
However, reading the bit on H.R. Pufnstuf I had to do a second take:
It claimed the show ran from 1969 to 1973 on NBC and then ABC, that was not strange, the thing that got me was, that the entry in the book, said that it only lasted 17 episodes!?!
In 5 years? I have to say I barely remember this show, since I was a toddler when it aired, (a few years later, and dub to spanish) but I have seen this show referenced many times, even in the SDMB, so I thought something that influential must have had dozens of episodes, but if the dates are right, that turns into only 3 or 4 episodes per year!
How did Sid and Marty Krofft managed to keep a series going for years with so few episodes?
