CBS was also hit, though not as severely: Paley's 1928 affiliate contract, which had given CBS first claim on local stations' air during sponsored time – the network option – came under attack as being restrictive to local programming.[74] The final compromise permitted the network option for three out of four hours during the daytime, but the new regulations had virtually no practical effect, since most all stations accepted the network feed, especially the sponsored hours that earned them money.[74] Fly's panel also forbade networks from owning artists' representation bureaus, so CBS sold its bureau to Music Corporation of America, and it became Management Corporation of America.[75]
