The 1980s were the golden years for South Korea's television industry. Growth was phenomenal in every dimension: the number of programming hours per week rose from 56 in 1979 to nearly 88.5 in 1989; the number of television stations increased from 12 in 1979 to 78 by 1989; and the number of television sets grew from four million in 1979 to nearly six million in the same period. Despite producing color televisions for export, color television was not officially introduced in the country until late 1980. Color broadcasting, however, occasioned a renewal of strong competition among the networks. However, the South Korean TV industry was also suffered huge blows in this decade. During Chun Doo-hwan's regime, several newspapers, broadcasters and publications were forcibly closed, or were merged into a single organization. One of which is TBC-TV which was awarded to KBS. TBC-TV was then replaced by KBS 2TV. After the country's 1987 democratic reforms, several regulations were imposed to insulate broadcasters from political influence. For example, the National Assembly established the Foundation for Broadcast Culture to insulate MBC from political influence and KBS.
