Tim probably watched Dallas.
Tim was definitely a Falcon Crest guy. Always not the popular shows. Lol
For 1978, I really don't remember watching many of these shows. I know we definitely had on Happy Days.
I remember Cliffangers, the Hulk, and Mork & Mindy.
We definitely watched Disney on Sunday nights, though I'm not sure at what point we stopped.
78-79 would've been 5th grade.
