Guessing 1969, because I think it was around the same time my son was born.

I'll guess 1975 (I seem to be doing a lot of that lately - guessing!) LOL

Seems like it started when I was in HS.. so I'll guess 1976.

I remember my eldest watching it, and she was born in 1973 and it had been around for some time at that point.

Around 1966. My husband knew Veryl Shult, who as a Dept of Ed person was involved in the program.

I have no idea. Yesterday I guessed Mildred because it was my Mother-in-law's name and Anna because it was my mother's name. LOL

No idea about the date of the debut of the "Sesame Street" gang ... but they were talking about it on the radio the other day, and may have given the date, but I don't remember.

Did Anna ... Eleanor ...

... write I O Us?
