The global media system is now dominated by around 50 giant firms, with the top 9 firms thoroughly dominating many sectors of film, TV, publishing, and music production. These firms are highly concentrated and engage in joint ventures that reduce competition. The system promotes commercial values over quality journalism or cultural diversity. It privileges genres like sports and entertainment that are lucrative for advertising over other types of content. This concentration of media power threatens democracy, yet it occurred with little public debate.
