GE radio ownership

[Doug Drown]

I know that GE at one time owned WSIX in Nashville and its TV counterpart, as well as WJIB in Boston; however, were WGY, KOA, and KGO the only radio stations that the company owned prior to, say, the '70s?  I've sometimes wondered why GE, with its deep pockets, never expanded its broadcasting interests early on in the way that Westinghouse did.  (It sold KGO to NBC back in the '30s, if memory serves).
