#5: H.R. Pufnstuf
Broadcasting from 1969 to 1970, with a substantial budget of $335,000 per episode, H.R. Pufnstuf stood as a pivotal children’s series by the Kroffts. Its financial success prompted NBC to extend its run with reruns on Saturday mornings for several additional years.

However, when NBC decided to sever ties due to profitability concerns, ABC quickly seized the opportunity to claim H.R. Pufnstuf, demonstrating how one network’s loss could become another’s gain. Today, the show enjoys cult classic status, celebrated for its imaginative storytelling, vibrant puppetry, and lasting impact on generations of viewers who fondly remember its whimsical charm.
