Concentration of media ownership

Concentration of media ownership, also known as media consolidation or media convergence, is a process wherein fewer individuals or organizations control shares of the mass media. Research in the 1990s and early 2000s suggested then-increasing levels of consolidation, with many media industries already highly concentrated where a few companies own much of the market. The proliferation of the Internet and with it the advent of new media companies challenged this oligopoly, before market share being again consolidated by a small set of companies.
