A media proprietor, also called a media executive, media mogul or media tycoon, is an entrepreneur who controls media that is consumed by many individuals through the personal ownership of or the holding of a dominant position within a media conglomerate or enterprise. Those with significant control, ownership, and influence of a large company in the mass media may also be called a business magnate. In more recent times, the creators and founders of social media platforms have also been considered media proprietors.
In the United States, newspaper proprietors first became prominent in the 19th century with the development of mass circulation newspapers. In the 20th century, proprietorship expanded to include ownership of radio and television networks, as well as film studios, publishing houses, online platforms, and other forms of multimedia companies. Reflecting this, the term "press baron" was replaced by "media baron" and the term "media mogul" (or "Hollywood mogul" when applied to people specifically working in the American film industry) was popularized in colloquial English. Media proprietors are likely to claim that their publications are editorially independent and unbiased, but this is often questioned. Social networking services such as Facebook are sometimes considered media companies due to their widespread influence. Media and technology play a significant role in the production of mass media.
