[1][2] Greece's least successful result was in 1998 when it placed 20th with the song "Mia krifi evaisthisia" by Thalassa, receiving only 12 points in total, all from Cyprus.

[4][5][6] However, in August 2013, the Greek government shut down the radio and television services of ERT, leaving Greece's future contest participation in question.

[11] On 4 May 2014, two days before to the 2014 contest's first semi-final, the new Greek public broadcaster, New Hellenic Radio, Internet and Television (NERIT), was launched allowing the participation for the year to formally proceed.

[13] NERIT confirmed on 14 January 2015 that it would partner with private music channel MAD TV to organize and produce Greece's selection process for the Eurovision Song Contest 2015, marking the third consecutive year of their partnership.

[16] NERIT put out a call for interest to major record labels to find participants for the show, resulting in five candidate acts.

[17] The five acts (Barrice, C:Real, Maria Elena Kyriakou, Shaya Hansen, and Thomai Apergi & Legend) were announced on 17 February 2015.

Five songs competed and the winner, "One Last Breath" performed by the Cypriot singer Maria Elena Kyriakou, was selected by a 50-50 combination of public and jury voting.

[32][33] To promote the song, Kyriakou appeared on 20 April at the Eurovision in Concert series, an event held at the club Melkweg in Amsterdam, Netherlands that was staged to serve as a preview party for the year's entries.

[35] Further promotional activities included Kyriakou performing live at the MAD TV annual fashion music series MADwalk on 29 April.

[38] Maria Kozakou and Giorgos Kapoutzidis provided commentary for the broadcasts, continuing a role they had performed together for the prior three contests.

[42] To determine when the semi-finalists would perform, the European Broadcasting Union (EBU) split up the competing countries into five different pots based on voting patterns from the prior 10 years.

[48][49] It saw Kyriakou wearing in a silver and black dress designed by Dimitris Petrou, and set to a background of a circle of blue LED lights.

[47] Immediately after the first semi-final, a winner's press conference convened for the ten countries that qualified, allowing their artists to participate in a draw determining their performance segment in the final.

This jury was asked to judge each contestant based on vocal capacity, the stage performance, the song's composition and originality and the overall impression by the act.
