As a propaganda tool, the state strictly controls the tone and subject material of all published works. State censors give preference to works that provide a positive, uplifting ideology to its readers. Criticism that passes the censors is limited to low and mid-level officers. Although the Karimov regime during the 1990s assumed a greater tolerance for foreign media, the state has heavily limited foreign publications during the past decade. There has been a considerable reduction of Russian-sponsored broadcasting, and Western media has diminished in publication as well.
