The political liberalization of the late 1980s brought a loosening of press restraints and a new generation of journalists more willing to investigate sensitive subjects, such as the May 1980 Gwangju massacre. Roh's eight-point declaration of June 29, 1987, provided for "a free press, including allowing newspapers to base correspondents in provincial cities and withdrawing security officials from newspaper offices." The South Korean media began a rapid expansion. Seoul papers expanded their coverage and resumed the practice of stationing correspondents in provincial cities. Although temporarily still under the management of a former Blue House press spokesman, the MBC television network, a commercial network that had been under control of the state-managed KBS since 1980, resumed independent broadcasting. The number of radio broadcast stations grew from 74 in 1985 to 111 (including both AM and FM stations) by late 1988 and 125 by late 1989. The number of periodicals rose as the government removed restrictions on the publishing industry.
