Congress has only the powers the Constitution grants it, and these are listed mainly in Article I. Broadcasting and telecommunications cross state lines, so Congress regulates them under the Commerce Clause. It created the FCC as an independent agency to administer that regulation, and the Necessary and Proper Clause backs that delegation. The question asks for an article, and that article is Article I.
- Article I, Section 8, Clause 3 gives Congress power to regulate commerce among the states and with foreign nations.
- The Communications Act of 1934 established the FCC and rests on this commerce power.
- Article I, Section 8, Clause 18 (Necessary and Proper Clause) supports creating an agency to carry out that power.
- Courts have long treated radio and telecommunications as interstate commerce, so they fall within federal regulation.
