Radio and television broadcasting, whose ownership structure had become increasingly concentrated since the 1980 Media Law, is regulated by a new law advanced by President Cristina Kirchner, and signed on November 11, 2009. This new policy would restrict the number of media licences per proprietor and allocate a greater share of these to the state and NGOs, thereby limiting the influence of the "Clarín Group" (the largest media conglomerate in Argentina) and other media companies, such as the conservative "La Nación".
