Mexico, located in the southern extreme of North America and northern extreme of Latin America, is the largest Spanish-speaking country in the world, with a population of 130 million. In Mexico, critical external and internal factors have contributed to the political, economic, and cultural dimensions and processes affecting the complex relationship between the country and its media systems, which were developed mainly as private enterprises, with some minor projects controlled by the state. This entry describes the evolution of that complex relationship through history and examines how academic research interprets and explains its main characteristics.
