I regularly run into shows and movies no one will carry.

A recent example is Hot l Baltimore. It's an early Norman Lear production and stared James Cromwell and Charlotte Rae.

I planned to add Turn On (1969), Tim Conway. It was canceled while the 1st episode was airing.

But since the last time I looked for it, some ethical soul uploaded it to wikipedia. https://en.wikipedia.org/wiki/Turn-On
