While only 1 percent of U.S. households owned at least one radio receiver in 1923, a majority would by 1931. The legislation created a five member Federal Radio Commission to provide oversight, with a commissioner appointed from each of five regional districts. The original law envisioned that after one year most of the Commission's work would be completed, after which "all the powers and authority vested in the commission under the terms of this Act, except as to the revocation of licenses, shall be vested in and exercised by the Secretary of Commerce; except that thereafter the commission shall have power and jurisdiction to act upon and determine any and all matters brought before it under the terms of this section". However, after a year it became clear that the commissioners needed more time, and in March 1928 their mandate was extended by a year. This reauthorization included a provision, known as the "Davis Amendment" after its sponsor Representative Ewin L. Davis (D-Tennessee), that required "a fair and equitable allocation of licenses, wave lengths, time for operation, and station power to each of the States, the District of Columbia, the Territories and possessions of the United States within each zone, according to population". In December 1929 the commission's mandate was extended indefinitely. Replacement by the Federal Communications Commission The Communications Act of 1934 abolished the Federal Radio Commission and transferred jurisdiction over radio licensing to the new Federal Communications Commission (FCC). Title III of the Communications Act contained provisions very similar to the Radio Act of 1927, and the FCC largely took over the operations and precedents of the FRC. The law also transferred jurisdiction over communications common carriers, such as telephone and telegraph companies, from the Interstate Commerce Commission to the FCC.
