the introduction of the vacuum -tube amplification for telephone lines allowed AT&T to experiment with sending speeches to distant audiences that listened  over loud speakers. The next step would be to use the lines to inter connect radio stations ,and December1921 ,the memo written by two AT&T engineers ,J. F Brantley and H . C Lauderback out lined the establishment of a national radio network ,financially supported by adverting  General electric , Westinghouse and RCA responded by forming their own radio network, however, unable to match AT&T progress ,in 1926 they bought  out AT&T's progress in 1926 they bought out AT&T's network operations ,which were reorganized to form the national broadcasting company. Creating competing national networks  proved difficult ,and over the next decade only two others would be established the Columbia broadcasting system in1927,andthe mutual broadcasting system in 1934.
