Yeni Şafak founding editor was Mehmet Ocaktan. In the beginning, Yeni Şafak was known for harboring both liberal and Islamist columnists. Yeni Şafak was acquired by Albayrak Holding in 1997, which had close ties with then mayor of Istanbul, Recep Tayyip Erdoğan. After İbrahim Karagül became the editor-in-chief of Yeni Şafak, the newspaper became a hardline supporter of then prime minister Recep Tayyip Erdoğan. More Islamist columnists were employed, while liberals like Kürşat Bumin were fired from the newspaper because of their critical views of Recep Tayyip Erdoğan and the AK Parti.
On August 26, Noam Chomsky accused the pro-government Yeni Şafak newspaper of fabricating parts of an interview that was done with him via email, including inventing questions and answers and altering criticism of Erdoğan's approach to Egypt and Syria into an assertion that Turkey "stood with the oppressed people in Syria and Egypt". The administration of Yeni Şafak denied the accusation and promised to release the original English content of the emails. However, the released original was full of grammatical mistakes. Later it was found out that Yeni Şafak used Google Translate to translate fabricated Turkish content into English, and presented the translation as the original interview. After the grammatical errors, particularly "milk port", became a sensation on social media, Yeni Şafak finally admitted some parts were fabricated and removed the entire interview from its web site.
Yeni Şafak newspaper was a primary source of disinformation during 2013–14 protests in Turkey. According to a report published by Hrant Dink Foundation, Yeni Şafak was the primary newspaper generating hate speech against Gezi protesters. PM Recep Tayyip Erdoğan said that they would release security camera footage to prove this had occurred. However, the imam of Dolmabahçe Mosque denied the paper's allegations and no footage was released to the public. Later, the imam was transferred to a different city. The paper also claimed a headscarved woman was attacked by a gang of shirtless protesters near Dolmabahce Mosque at a tram station on June 1, 2013. On February 14, 2014, several months after the protests had ended, security camera footage showed that there had been no attack on a woman wearing a headscarf by protesters on that date. The woman and Prime Minister Erdoğan had claimed in press conferences and political rallies that protesters had attacked her and her baby. On June 10, Yeni Şafak claimed that a theatrical play called "Mi Minor," allegedly supported by an agency in the United Kingdom, had held rehearsals for a "revolution" in Turkey for months. On July 14 Yeni Şafak published an article, titled "The Gezi Protestors' Horrible Plan for Istanbul," on their website that claimed that Gezi protesters were conspiring to undermine the government by wasting water from the reservoirs supplying Istanbul. After the article became the object of nationwide mockery, Yeni Şafak removed it from their website.
Other disinformation incidents
On January 15, 2016, Yeni Şafak published a video purportedly showing live audience members of the prime-time Beyaz Showtalk show chanting slogans in support of outlawed Kurdish leader Abdullah Öcalan. British investigative news agency D8 News published a forensic analysis demonstrating that the audio track was modified before publication, adding voices sampled from an unrelated protest. The article also presented evidence that Yeni Şafak editors likely attempted to cover up their claims rather than issuing a formal retraction. The falsification incident was subsequently corroborated and covered by other news outlets in Turkey.
Anti-Semitism
On July 11, 2014, Yeni Şafak columnist İbrahim Sancak resorted to hate speech against Jews. On July 11, 2014, Yeni Şafak columnist Yusuf Kaplan resorted to hate speech against Jews. On July 23 and 30 2014, Yeni Şafak columnist İbrahim Tenekeci resorted to hate speech against Jews and identified them as "eternal pain of humanity".
Anti-LGBT
On June 6, 2012, Yeni Şafak columnist A. Fuat Erdoğan identified homosexuality as perversion. On May 13, 2013, Yeni Şafak columnist Yusuf Kaplan identified sexual identities other than heterosexuality as perversion.
Anti-Abortion
On June 6, 2012, Yeni Şafak columnist A. Fuat Erdoğan resorted to hate speech against pro-abortion women.
