I know this has been brought up before, but check out this newscast from WQAD in 1990. This is the era when they used the WCCO '85 Theme, This clip obviously includes bumpers to this package, that I am hearing for the first time. Was curious if this sounds familiar to anyone. I know this package was used by several stations and I have been really wanting to figure out who created it, its a great package. Below are other clips of this package.

(The last clip from WMBD is a long shot, but you can hear very briefly at the end of that promo is the same as the end off the KSNW promo, point being is this package was widely used)
