Although a relatively stable democracy, Chile continues to suffer from corruption and hangovers from the military dictatorship. Pluralism and democratic debate are badly limited by the concentration of media ownership and the difficulties that community media encounter in ensuring their long-term survival. Despite significant progress in access to information and Internet use, reporters still have problems covering certain subjects such as the demands of the Mapuche communities, which have been in conflict with the Chilean state for nearly 200 years. Several radio stations have been shut down in recent years. In 2016, several journalists who were investigating corruption cases implicating officials and associates of former President Michelle Bachelet were the targets of arbitrary defamation lawsuits.
