- the Federal Radio Commission with its authority over radio,
- authority over telephone, telegraph, and cable companies from the Interstate Commerce Commission

Government officials had been unhappy with the Interstate Commerce Commission's oversight of communications carriers, as the ICC has been entirely preoccupied with railroad regulation. AT&T was also seen as growing in political power, which it was effectively leveraging at the state public utility commission level.
In 1933, a Department of Commerce Committee recommended that "the communications service, as far as congressional action is involved, should be regulated by a single body." In February 1934, Franklin D. Roosevelt sent a special message to Congress urging the creation of the Federal Communications Commission (FCC). The Communications Act was signed into law by President Roosevelt on June 1934.
