Maybe I'm just telling my age, but TV got into our home
when I was maybe 8 or 10 years old.
I never listened to"Radio Shows" at all until perhaps within
the past 10 years, however.

Back in the "good old days", radio was the entertainment of the day.
I won't go into nostalgic lists of what people listened to except
to mention a few I particularly like pulling up from "Old Time Radio"...
But first, to mention one of a number of places to listen to old time
radio shows, check out http://www.archive.org which archives ALL
kinds of media !
