For local government, public notice is often given by those seeking a liquor license, a rezoning or variance, or other minor approval which must be granted by a city council, county commission, or board of supervisors.
Public notices are sometimes required when seeking a new broadcast license from a national broadcasting authority, or a change to modification to an existing license.
U.S. broadcast stations are required to give public notice on the air that they are seeking a license renewal from the U.S. Federal Communications Commission (FCC), or to notify viewers of the station's purchase by another party. Records of these public notices must often be kept in a station's public file.
One method of notice is publication of a public notice ad in a local newspaper of record. Public notice can also be given in other ways, including radio, television, and on the Internet. Some governments required publication in a local/nationwide newspaper or the government gazette, though there have been attempts among some politicians to eliminate the expense of publication by switching to electronic forms of notification.
