I do too and liked both shows, but this guy seems to imply that those were the “main” shows watched. Obviously that was not the case as “Three’s Company” and “One Day at a Time” were the popular shows (at least late 70’s.)
Seems his age is probably off by about 10 - 15 years because The Donna Reed Show aired from 1958 - 1966 which would mean he was probably born in the late 40’s or early early 50’s at the very least if it were one of the main TV show of his day. He may be getting senile in his old age too...lol
The author doesn’t imply that the programs to which you refer were the main shows of his childhood. In fact, he doesn’t even mention them. The picture posted with the article is an editorial addition that has nothing to do with the substance of the piece.
