The Eighties marked a return to Single Dad TV shows' focus on the relationship between Dads and their kids in the home environment
. Careers of the Single Dad took the back seat in story development.
Novel mixes of "tag-team Dads" appeared, slightly altering the definition of the Single Dad. Could you really identify someone as a "Single Dad" if they lived with another "Single Dad?"
Also, notice the downsizing of the TV Single Dad families - most of the families in the 80's shows had only one child. Quite a paring-back from the 60's troikas.
