I want to know the answer to the following question:
Along with MOR, easy listening and soft rock, what format is soft adult contemporary a successor to?
All the background I'm provided with is that "Many stations in the soft AC format capitalize on its appeal to office workers (many of them females aged 25–54, a key advertiser demographic), and brand themselves as stations "everyone at work can agree on" (KOST originated that phrase as a primary tagline, and other soft AC stations have followed suit).". Is that enough to answer the question?
Answer: no
