I want to know the answer to the following question:
When did E.K. Gaylord's Oklahoma Publishing Compan buy WKY Radio?
All the background I'm provided with is that "In 1928, WKY was purchased by E.K. Gaylord's Oklahoma Publishing Company and affiliated with the NBC Red Network; in 1949, WKY-TV (channel 4) went on the air and later became the first independently owned television station in the U.S. to broadcast in color.". Is that enough to answer the question?
