The Dong-a Ilbo
In December 1974, "The Dong-a Ilbo", one of the largest newspapers in South Korea, and its subsidiaries began to release media with empty advertisement slots in protest against Park's strict censorship laws. "The Dong-a Ilbo" had a long history of defying and protesting the authoritarian governments in Korea, and had been in dispute with Park since he led the Supreme Council of National Reconstruction. The Korean Central Intelligence Agency began to force "The Dong-a Ilbo"'s main advertisers to withdraw, and the company relied on small advertisers until it was eventually pressured by the government into ending its protest campaign seven months later. The incident resulted in employees being dismissed, many of whom co-founded the popular newspaper "The Hankyoreh".
