The Turkish participating broadcaster, Türkiye Radyo ve Televizyon Kurumu (TRT), internally selected its entry for the contest.

On 17 December 2007, TRT announced during a press conference that it had internally selected the band Mor ve Ötesi to represent Turkey in the Eurovision Song Contest 2008.

[2] Three songs were submitted by the band to the broadcaster in January 2008 and a nine-member selection committee consisting of Muhsin Mete (TRT deputy general manager), Deniz Çakmakoğlu (TRT deputy head of music), Kürşat Özkök (Ankara Television manager), Ümran Sönmezer (TRT polyphonic music director), Neşet Ruacan (conductor at the TRT Istanbul Light Music and Jazz Orchestra), Kamil Özler (member of the TRT Istanbul Light Music and Jazz Orchestra), Can Sertoğlu (manager of Mor ve Ötesi), and two members of the band Harun Tekin and Kerem Özyeğen selected "Deli" as the song they would perform at the contest.

Although Turkey had been granted a spot in the 2008 final because of its fourth-place finish at the Eurovision Song Contest 2007, it had to compete in a semi-final because of new rules put into effect by the European Broadcasting Union (EBU).
