Copyright law applies to podcasts as it covers creative works such as interviews, scripts, music and sound recordings. Once a work is fixed in a tangible form, such as writing or recording, copyright is automatically granted. Podcasters must secure permission from copyright holders to use their work and ensure any interviews or adaptations have consent. Fair use allows limited copying for purposes like commentary but factors like use, work type, amount taken and commercial impact are considered. Podcasters should use Creative Commons licensed content when possible but must have permission to use other copyrighted material.
