The term "objectivity" was not applied to journalistic work until the 20th century, but it had fully emerged as a guiding principle by the 1890s. Michael Schudson, among a number of other communication scholars and historians, agree that the idea of objectivity has prevailed in dominant discourse among journalists in the United States since the appearance of modern newspapers in the Jacksonian Era of the 1830s. These papers transformed the press amidst the democratization of politics, the expansion of a market economy, and the growing authority of an entrepreneurial, urban middle class. Before then, American newspapers were expected to present a partisan viewpoint, not a neutral one.
