Transparency of media ownership is the public availability of accurate, comprehensive and up-to-date information about media ownership structures. A legal regime guaranteeing transparency of media ownership makes possible for the public as well as for media authorities to find out who effectively owns, controls and influences the media as well as media influence on political parties or state bodies. The disclosure of media ownership can be prescribed by generic regulation (commercial law) or by media-specific provision. Such measures may mandate the disclosure of information on media ownership structures to specific authorities or to the general public.
