Estructura y dimensión de las industrias infocomunicacionales en América Latina Guillermo Mastrini Martín Becerra Comunicación mercados industrias culturales industrias infocomunicacionales Este artículo presenta resultados parciales de la investigación Estructura yconcentración de las industrias culturales y las telecomunicaciones en AméricaLatina, que dirigieron los profesores Guillermo Mastrini (Universidad de BuenosAires) y Martín Becerra (Universidad Nacional de Quilmes), y que desarrollaroncon un grupo organizado por el Instituto Prensa y Sociedad (IPyS). Lainvestigación detalla, con datos sobre el año 2000, la estructura de las industriasde la cultura, la comunicación y la información en Argentina, Bolivia, Brasil, Chile,Colombia, México, Perú, Uruguay y Venezuela. Así mismo, se establece unacomparación basándose en los indicadores de acceso y facturación que permitenobservar el tamaño de los mercados de prensa escrita, libro, disco, cine, televisiónabierta y de pago, radio y telefonía fija y telefonía móvil, sobre el desarrollo y elimpacto del sector en América Latina. 2005 artículo científico 0122-8285 https://www.redalyc.org/articulo.oa?id=64901201 es http://www.redalyc.org/revista.oa?id=649 Palabra Clave application/pdf Universidad de La Sabana Palabra Clave (Colombia) Num.12
