Sistema Público de Radiodifusión del Estado Mexicano

The Sistema Público de Radiodifusión del Estado Mexicano (SPR, English: Mexican State Public Broadcasting System), known as Organismo Promotor de Medios Audiovisuales (OPMA, English: Broadcast Media Promotion Organization) until 2014, is an independent Mexican government agency. Its mission is to support the development of public television in the country and increase its national reach; it carries this goal out through ownership of a nationwide network of transmitters and the operation of its own public television network. The agency was established by a decree published on March 31, 2010.

By 2010, two major public television stations existed in Mexico: the Instituto Politécnico Nacional's Canal Once, Conaculta's Canal 22. In addition, the low-powered test signal XHUNAM-TDT channel 20 and the teveunam pay TV network, owned by the largest public university in Mexico, UNAM, had been in operation since 2000 and 2005, respectively. However, not all of these stations, especially Canal 22 and teveunam, had national coverage outside of pay television services. None of them had a general national reach above 30%. Even then, major cities, including Guadalajara and Monterrey, were not in Canal Once's signal footprint.

OPMA was established with the mission of ensuring that more Mexicans could receive a wider range of public television signals. Indeed, when the first four OPMA transmitters took to the air on July 12, 2010, national coverage for Canal Once (then known as Once TV México) jumped from 28 to 42%; it is now at 66%.

The 2014 Mexican telecommunications reform transformed OPMA into SPR, effective August 13, 2014. At the same time, the system became an independent agency no longer under the auspices of the Secretariat of the Interior (SEGOB).

On August 26, 2015, the IFT awarded the SPR concessions for seven new TV stations and two radio stations.

SPR's flagship television network, Una Voz con Todos (A Voice for All), abbreviated as UVTV, broadcasts documentaries and other programs. Its programming is designed to strengthen the democratic values of Mexican society.

SPR's transmitter network currently covers 56% of the Mexican population. The flagship station is XHOPMA-TDT in Mexico City. Ten transmitters, denoted with asterisks, carry Canal del Congreso.
