Public broadcasting includes radio, television and other electronic media outlets that receive some or all of their funding from the public. Public broadcasters may receive their funding from individuals through voluntary donations, a specific charge such as a television license fee, or as direct funding by the state.
The extent to which public broadcasters can be considered "non-commercial" varies from country to country. In the United States most public radio and television stations are licensed as non-commercial broadcasters, yet many stations transmit underwriting spots (resembling advertisements on commercial broadcasting but with some content limitations) in exchange for corporate contributions. In some other countries public broadcasters are permitted to transmit commercials.
