This is somewhat interesting to me, because in essence, the adult standard format description you describe was completely foreign in the pre-1960 days of KIXI. It was, in fact, mainstream radio, or "middle of the road" at the time. I was not yet born, but my research indicates that this is what the norm was for many radio stations. So Seattle stations like KING, KIRO, KVI, KOMO, and perhaps KJR (prior to the late 50's) all presented a similar musc format, (with slight variations), but always with personality and news. Things began to change around 1960, with KAYO and KJR going more contemporary, followed by KOL. KOMO and KIRO, and to some extent KVI, stayed with their mainsteam (or even MOR) formats into the 70's, but soon it was evident that the FM's would change that. KIRO and lesser known KTW were among the first to pick up on the changes and added news and/or talk in the early 70's, although KING had a night time talk show well before its adventure into Top40 in 1971.
