Starting tonight, viewers can watch Norman Lear's original CBS sitcom that aired from 1975 to 1984 for free on Pluto TV, which has timed it with the revival's premiere tonight on Pop TV. ViacomCBS owns both Pluto TV and Pop TV. Pluto TV has acquired the rights to the original One Day at a Time for a limited from Sony Pictures Television.

I just saw this. This is great. It also has All in the Family. Would be nice if it had Maude and The Jeffersons too but it’s still great. Nice to have some sitcoms from this time period on Pluto. I’ll definitely be watching One Day at a Time

Looks like it’s gone now unfortunately

And it is back on Pluto thank goodness

How do you find out what shows air at what times on Pluto? There is no guide that gives you a preview of what will air.
