While specific policies differ from community to community, in general, Public Access channels are meant to be available to everyone. You can provide a program for the Access operator to play or, in some communities; you can get training and use equipment to produce your own program. See what is available in your community.
Educational Access channels are usually used by schools to show educational television, telecourses, or information about local schools and resources. Here in Contra Costa County, Educational Access television is provided by the Contra Costa Educational Television Consortium.
Government Access television allows local City and County governments to serve their communities by providing information about local resources, services, and emergencies. Coverage of local City Council and Board of Supervisors meetings, allow the public to see how local government runs and how its elected leaders make decisions.
