A media conglomerate, media company, media group, or media institution is a company that owns numerous companies involved in mass media enterprises, such as music, television, radio, publishing, motion pictures, video games, amusement parks, or the Internet. Despite ownership over several companies and diverse mediums, by definition, media conglomerates only maintain holdings over media and not other enterprises.
Some media conglomerates use their access in multiple areas to share various kinds of content such as: news, video and music, between users. The media sector's tendency to consolidate has caused formerly diversified companies to appear less diverse to prospective investors in comparison with similar companies that are traded publicly and privately. Therefore, the term media group may also be applied, however, it has not yet replaced the more traditional term.
