Spectrum scarcity: The electromagnetic spectrum used for broadcasting is a limited resource, and the government needs to regulate its use to prevent interference and ensure fair access. Print media, on the other hand, does not face this constraint.
Public interest: Broadcasting has a broader reach and can have a more significant impact on public opinion compared to print media. Regulating broadcast media allows the government to ensure that it serves the public interest by providing diverse content and protecting vulnerable audiences.
Historical precedent: The regulation of broadcast media has a long history dating back to the early days of radio and television. The government's role in regulating broadcasting has been upheld by the courts and is now well-established. Print media, on the other hand, has a longer history of freedom from government regulation.
Technological differences: Broadcast media can transmit content instantaneously to a wide audience, while print media requires a physical medium (e.g.,报纸、杂志) to be distributed. These technological differences have influenced the regulatory approaches taken for each type of media.
It's important to note that the level of regulation for broadcast media varies across countries and can evolve over time. Some countries may have stricter regulations on broadcast content, while others may allow more freedom.
