The Basic Rationale for Heavier Government Regulation of Broadcasting Than

The basic rationale for heavier government regulation of broadcasting than of the print media is that:

A) radio and television are entertainment and have no First Amendment protection.
B) the propaganda potential of the electronic media is so great that more protection is needed.
C) broadcasters are given the exclusive use of a scarce resource (the radio spectrum) and must use it "in the public interest,convenience and necessity."
D) broadcast advertising is too pervasive and persuasive to be left unregulated.
E) the broadcast media are more technically complex and need more government assistance to maintain good technical standards.
