Returning home in 1963, Cem started his professional career as a journalist. He worked in some major newspapers who published articles and became a columnist for Milliyet, "Cumhuriyet" and Politika, where he served as the editor in chief for the second newspaper from 1964 until 1966. Between 1971–1974, he served as the chief of the Istanbul office of the Turkish Newspaper Workers Union. In 1974–1975, he acted as the general manager of the state-owned Turkish Radio and Television Corporation under the 37th and 38th governments. Cem's tenure as the general manager of TRT, then the only TV station in Turkey, created some controversy. The conservatives and prominent right-wing figures like future President of TurkeySüleyman Demirel used their political and social influence to remove İpekçi from his post in several attempts, which have all proven fruitless.
Writing career
Among with his political and journalistic successes, İpekçi is also known as one of the ideologists of social democracy in Turkey, and was counted among the prominent figures within the Turkish centre-left. İpekçi, who advocated a moderate agenda in a time of political turmoil, wrote extensive accounts of the economic and social factors lying beneath Turkey's underdevelopment and theoretized methods for the revitalization of Turkish left. Among his books are Turkiye'de Geri Kalmışlığın Tarihi, one of the most acclaimed books in the field of social sciences in Turkey and Sosyal Demokrasi Nedir?, Ne Değildir?, one of the first books to introduce social democracy to Turkish politics.

He is also labeled as the visionary of the . A more detailed bibliography of his works can be found below.
İpekçi and his Greek counterpart George Papandreou worked to improve Turkish-Greek relations. It is during his tenure as foreign minister that a confident, albeit a step-by-step approach was taken towards a rapprochement between Turkey and Greece. The relations were actually at an all-time low after the Abdullah Öcalan affair, whereby Greek Foreign MinisterTheodoros Pangalos and some officials of the Greek Foreign Ministry were involved in hiding organization PKK leader prior to his arrest by the Turkish police. İpekçi and Papandreou picked up the historically hostile relationships initially starting with some confidence measures.
Later political career and illness
After a dispute with the party leader Bülent Ecevit, he resigned from the Democratic Left Party ahead of 2002 parliamentary elections and formed the New Turkey Party on 20 July 2002 together with his former party colleague Hüsamettin Özkan. İsmail Cem was elected leader of YTP, which did not do well in the elections. Returning from the United States, where he was due to medical treatment of cancer, he closed YTP on 24 October 2004, joining the CHP. İsmail Cem was acting as the chief advisor to Deniz Baykal, the leader of CHP, and lectured in Applied Foreign Politics of Turkey at the Istanbul Bilgi University until his death. He was married to Elçin Cem, and the couple had a daughter, İpek Cem Taha, and a son, Kerim Cem.
İsmail Cem was especially admired by young people in Turkey during his time as a foreign minister. Some polls indicated that young people desired to see Cem as President of Turkey. İsmail Cem's biography written by Turkish political scientist Ozan Örmeci, and its Turkish version found many readers among Turkish intellectuals and showed Cem's unique place in Turkish social democratic movement.
