Which organization formed the first radio network in the United States?

• A. RCA
• B. NBC
• C. The Broadcast Corporation of America (first radio network made by AT&T)
• D. CBS

Answer: (C)

The question is about the origins of network radio in the U.S. and how the first nationwide system came together. In the early 1920s, AT&T built a national network by linking distant radio stations through its long-distance telephone lines, so programs could be aired coast-to-coast. The organization they used to oversee and operate this effort was The Broadcast Corporation of America, effectively AT&T’s vehicle for creating that first nationwide network.

That early network predates the later rise of NBC and CBS, which formed from RCA-backed and other efforts in the mid to late 1920s. So the option describing The Broadcast Corporation of America as AT&T’s first radio network makes sense as the historical origin of the nation’s networked radio.
