Mexico is planning a $45.5 million boost to public broadcasting, to rough triple national coverage from 2010 to 2012, Variety reports. That initial investment for 2011-2012 will mainly fund 19 new repeater substations to help boost signals across the nation. An additional $3 million yearly will go to operations through 2020. The government hopes to improve the coverage of Once (Spanish for 11) TV, the largest educational broadcast network (owned by Instituto Politecnico Nacional, or the National Polytechnic Institute), from 50.7 percent to 76.8 percent of the country, an additional 26.9 million viewers. Its goal is to reach more than 91 million viewers by 2020. Some 79 percent of television sets in Mexico rely solely on over-the-air broadcasting.
