Trabajadores intelectuales e industrias culturales Daniel E. Jones Comunicación Este artículo analiza la relación existente entre los diferentes tipos de “trabajadores intelectuales” y las “industrias culturales y comunicativas” des de una perspectiva crítica. Este amplio colectivo —dentro del cual los intelectuales “puros” serían solo una pequeña parte, aunque muy relevante—, se caracteriza por estar constituido por un conjunto de personas cuyo estatus social y laboral le viene dado, en buena medida, por su mayor o menor relación de dependencia económica con las empresas que conforman las industrias culturales y comunicativas, productoras y comercia liza do ras de cultura y comunicación de élite y de masas, preferentemente privadas, tanto nacionales como transnacionales. El artículo estudia la interrelación de los trabajadores intelectuales con estas empresas culturales y comunicativas y no las pos turas de aquellos frente a estas, fenómeno este último que ha dado lugar a una abundante y contradictoria bibliografía entre los que han sido llamados “apocalípticos” y los “integrados”. 2006 artículo científico 1025-9945 https://www.redalyc.org/articulo.oa?id=570667392011 es http://www.redalyc.org/revista.oa?id=5706 Contratexto application/pdf Universidad de Lima Contratexto (Perú) Num.14
