The workers' movement has long recognized the importance of the press and other cultural institutions in developing and sustaining class consciousness and the movement itself. Hundreds of workers' newspapers were established throughout the United States by labor unions, working-class political organizations, and sympathetic editors. These papers, ranging from hand-written, locally-circulated sheets to national daily newspapers published in regional editions (many published in foreign languages), were later supplemented by news services, broadcasting and (more recently) public relations campaigns. While scattered studies of individual newspapers and foreign-language newspapers published by immigrant socialists exist, little research into the operation, content, and influence of labor publications has been conducted as yet.
