I was in my single digit years old when some of these shows aired. I was weaned on the likes of these.
It was called quality programming. Something we no longer see on Saturday mornings for today's kids. They weren't juiced up cartoons featuring cartoon characters doing amazing feats of unrealistic fantasy. Unbeknownst to us, at the time, they we not only entertaining but educating us at the same time.

And so, so many more. There was Rin Tin Tin, Fury, Sky King, Howdy Doody Time, Kukla, Fran, and Ollie and others.
I suppose the point to made here is that kids today have unrealistic expectations because of the current crop of Saturday mornings shows. Shows which feature super heroes doing fantastic out-of-this-world unrealistic things. Whereas these programs back then featured real people. Real kids. Doing simplistic real things in the real world in which they live.
Corny as they were, there's just something about them.
