戰後初期,台灣發行的全島性報紙都相當重視國際新聞與中國大陸新聞,這些國際新聞包括美國對華政策、聯合國大會消息等。從版面配置來看,國際新聞大多放在頭版,這表示編輯有意藉此吸引讀者,同時也顯示民眾關心世界動向。因此,當1946年7月間東京澀谷發生日警槍殺台灣人的事件時,台灣媒體都有詳細的報導。當時,台灣報紙的國際新聞大多仰賴中央社的電訊。但是,還是有部份報紙派出記者到日本,進行實地的採訪報導。有關澀谷事件,各報都刊載許多消息與評論,充分突顯新聞自由之景象。然而,澀谷事件之後,台灣社會內部日益紛擾,民眾對國際事務的關心也大幅降低。戰後初期台灣新聞自由的喪失,雖然與二二八事件有密切的關聯,但是從澀谷事件報導的變化,才能更充分說明整個演變過程。亦即,戰後初期曾經存在短暫新聞自由,特別是國際新聞部分,但隨著局勢的演變,新聞管制逐步地確立,台灣島內外消息的傳遞都逐步被全面封鎖。
After the world War II, the newspapers published in Taiwan were full of the international and mainland China news such as the United States China policies and meetings held in the United Nations. From the newspaper's layout, one could see that newspapers used the international news to attract readers by putting the international news on the cover page. By the same token, this also a sign that people were interested in the international affairs. Therefore, when Japanese policemen gunned down Taiwanese in Shibuya Tokyo in July 1946, the incident was widely published in Taiwan newspapers. There were some journalists went to Japan to obtain the firsthand information even the media main source for the international news was China News Agency at that time. There were many different voices, critiques and analysis published in newspapers after the Shibuya event which reflected the full scope of media freedom in Taiwan. However, after the Shibuya incident, the degree of media freedom was greatly reduced and people seemed no longer interested in the international affairs. Although the increase of restriction on media after the war was highly related to the 228 incident, the Shibuya event demonstrated the process of how the media climate had changed in Taiwan. From the flourished but short-lived media freedom, then followed by restriction especially toward the oversea news, and finally came to the total prohibition on the publication of domestic and international news.
