What if GE bought Cox in the 70s? Would they have still bought NBC? Would WSB move back to NBC? By then, NBC was the top network.
Here is the list of stations GE owned in the 1970's before they divested them to get NBC in 1986.
WNGE-TV changed ownership from General Electric Broadcasting to Knight-Ridder Broadcasting on November 28, 1983. WSIX radio stations were sold to Sky Communications of New York. Knight-Ridder changed the call letters to WKRN-TV (W-Knight-Ridder-Nashville). Young Broadcasting, Inc. acquired WKRN-TV from Knight Ridder Broadcasting on July 1, 1989.
