Speaking of Black 70s TV shows, I was struck with the following memory.
I was raised in Northern Canada. For some reason, 80% of Canada gets all it's American, i.e. good, television programming out the Detroit affiliates. Therefore, even though we lived thousands of miles from a real city with any diversity, all of the daytime syndicated television shows starred African-Americans. I still remember being about 5 years old at the babysitter's watching "The Jeffersons" with all the other kids. Ten blonde heads swaying with the rhytm and blues theme song. Alas, we didn't know that we didn't have soul until someone told us.
