It was Grebe's hope to expand the Atlantic Broadcasting Company into a network operation, now that NBC has shown the way. But in September 1928, an opportunity arose that would make this station one of the major players in radio history. The Columbia chain did not own an outlet in New York. Its local affiliate was Bamberger's WOR, which was sure it could produce local programs of equal quality. When WOR refused to clear additional time for the CBS network, WABC stepped in to become the second affiliate, a move it hoped would justify a power increase. For a few weeks in 1928, WABC was the CBS station on Sunday, Tuesday, and Thursday, with WOR carrying the network on the other four days, but soon WOR dropped CBS completely.
In November 1928, Columbia offered to buy either of its New York area affiliate, and President William S. Paley negotiated with both Grebe and Bamberger. WOR's facilities were superior, but Paley chose the less-expensive WABC, and in December [1928] the Atlantic B broadcasting Company became a subsidiary of CBS. The sale price was $390,000, though the appraised value of the studios and transmitter was just $130,000. Grebe had apparently let the WABC studios go to seed, for Paley reported a mess on the seventeenth floor of Steinway Hall. Among the assets were goods accepted as payment from sponsors; jewelry, kitchenware, and reportedly even some live chickens.
