In mass communication, media are the communication outlets or tools used to store and deliver information or data. The term refers to components of the mass media communications industry, such as print media, publishing, the news media, photography, cinema, broadcasting (radio and television), digital media, and advertising.

Regulations The role of regulatory authorities (license broadcaster institutions, content providers, platforms) and the resistance to political and commercial interference in the autonomy of the media sector are both considered as significant components of media independence. In order to ensure media independence, regulatory authorities should be placed outside of governments' directives. this can be measured through legislation, agency statutes and rules. Government regulations Licensing In the United States, the Radio Act of 1927 established that the radio frequency spectrum was public property. This prohibited private organizations from owning any portion of the spectrum. A broadcast license is typically given to broadcasters by communications regulators, allowing them to broadcast on a certain frequency and typically in a specific geographical location. Licensing is done by regulators in order to manage a broadcasting medium and as a method to prevent
