Why did the show move from ABC to CBS? Were the ratings dropping or was there another reason? Also, does anyone know if the ratings went up or down following the network change?

Also, what was the one-hour special about in 1972 and were there any reunion shows following the end of the series?

Thanks.

Don Fedderson sold the show to CBS in 1965, when it went to color, after ABC cancelled it. Don probably felt it would do better on CBS.
I never or don't remember seeing the one-hour special, in 1972, but, from what I've heard, I think it was a retrospective, with clips from past episodes. I first have been hearing rumors about a one-hour finale episode, where Steve has amnesia, but, I don't know if people think that's the same one-hour episode

PS;The ratings were substantially plummeting by the FINAL SEASON

I do have memories of the 1 hr specail, yes Steve fell down a flight of stairs of the basement and they used the clips to jogg his memoris but that's about I recall. and there was a reuion show of sorts in 1976 or 77 where EVERYONE was shown from Mike right on down to Polly perhaps someone could recall that show

The 1977 SPECIAL was a THANKSGIVING show, where the cast members of BOTH MY THREE SONS AND THE PARTRIDGE FAMILY reminisce respectively about their shows. From what I've heard, DAWN LYN(Dodie)was absent from the special
