These days, you can't escape reruns of The Golden Girls.
The series aired on NBC from 1985-92, and then shifted to CBS, where it underwent a title change to The Golden Palace, but bombed out after less than a year.
Set in Miami, the series was built around four seniors, including a mother-daughter tandem, facing typical sitcom situations, with equally typical results. The odd thing was, the mother figure, Sophia, was played by a relative newcomer, Estelle Getty, whie everyone else was, in truth, an old friend. Betty White (Rose) has been a TV staple seemingly forever, rapidly becoming the female equivalent of George Burns, as she looks like she could work until she reaches 100. Beatrice Arthur (Dorothy) & Rue McClanahan (Blanche) had previously teamed on Maude more than a decade earlier, so there was some chemistry there.
Currently, reruns air on TV Land, which means it might be cross-promoted on sister network Nick at Nite in due course, after stops at Lifetime, Hallmark, WE, & INSP. TV Land seems appropriate, largely because the venerable Miss White now stars in Hot in Cleveland, which just started its 3rd season last week.
Here's the open:
Betty White is the only one left out of the core cast, and, as noted, shows no signs of slowing down.
