One of the shows my mom liked to watch before I was born is reruns of Mary Hartman, Mary Hartman so that's why there's a lot of her. I found a few more tapes of the show that I'm going to check out. Sorry the quality isn't that good because obviously this was over 30 years ago. All commercials still come from Philadelphia but I suppose the channels were different back then (looks like it was on 48 WKBS.). My guess would be NBC? If I find anymore commercials I'll share.
