Prior to the 2020 contest, Greece had participated in the Eurovision Song Contest forty times since their debut in. The nation has won the contest once, in with the song "My Number One" performed by Helena Paparizou. Following the introduction of semi-finals for the 2004 contest, Greece managed to qualify for the final with each of their entries for several years. Between 2004 and 2013, the nation achieved nine top ten placements in the final. To this point, Greece in with Argo's "Utopian Land" failed to qualify from the semi-finals for the first time ever, being absent from the final for the first time since 2000, marking Greece's worst result at the contest. In the 2018 contest, Greece failed to qualify for the second time with Yianna Terzi and the song "Oniro mou" finishing 14th in the semi-final. Greece returned to the final in 2019 with Katerine Duska and the song "Better Love", placing 21st with 74 points. The Greek national broadcaster, Hellenic Broadcasting Corporation, broadcasts the event within Greece and organises the selection process for the nation's entry. ERT had been in charge of Greece's participation in the contest since their debut in 1974 until 2013, when the broadcaster was shut down by a government directive and replaced with the interim Dimosia Tileorasi and later by the New Hellenic Radio, Internet and Television broadcaster. On 28 April 2015, a legislative proposal that resulted in the renaming of NERIT to ERT was approved and signed into law by the Hellenic Parliament; ERT began broadcasting once again on 11 June 2015. The new ERT then confirmed their intentions to participate at the 2016 Eurovision Song Contest on 28 August 2015. The Greek broadcaster has used various methods to select the nation's entry in the past, such as internal selections and televised national finals to choose the performer, song or both to compete at Eurovision. In early September 2019, Maria Koufopoulou, ERT's Director of International Relations, confirmed that the country would participate in the 2020 contest. She also stated that they were still evaluating how to select the entry and were in discussions with local fan clubs to solicit ideas.
Before Eurovision
Internal selection
Similar to 2019, ERT announced that the Greek entry would be selected internally by the broadcaster. On 15 January, it revealed the names of the people who would comprise the jury panel involved with the selection of the entrant. The jury consisted of music composer and ERT board member Dimitris Papadimitriou, music producer Petros Adam, Yiorgos Markakis, music producer Yiannis Petridis, and ERT's Director of International Relations Maria Koufopoulou. Prior the official announcement of the performer, Star Channel reported that seven acts had been shortlisted to represent Greece in Rotterdam, including Irini Papadopoulou, Stefania, Ian Stratis, and the boy band One. They reported that the jury would listen to the songs submitted by each act before selecting their preferred entry. On 3 February 2020 during an ERT newscast, Stefania was announced as the Greek entrant with the song "Supergirl". The song was written by Dimitris Kontopoulos, Sharon Vaughn, and the production team ARCADE. Born in the Netherlands to a family with Greek ancestry, Stefania had previously represented the Netherlands at the Junior Eurovision Song Contest 2016 as part of the group Kisses, placing eighth. The song and accompanying music video were released the following month on 1 March 2020, during the premiere of ERT's new program Eurovision Song Contest - Final Countdown, hosted by Mihalis Marinos. The music video was directed by Konstantinos Karydas.
At Eurovision
The Eurovision Song Contest 2020 was originally scheduled to take place at Rotterdam Ahoy in Rotterdam, Netherlands and consist of two semi-finals on 12 and 14 May, and a final on 16 May 2020. According to Eurovision rules, each country, except the host nation and the "Big 5", would have been required to qualify from one of two semi-finals to compete for the final; the top ten countries from each semi-final would have progressed to the final. On 28 January 2020, the allocation draw was held at Rotterdam City Hall, placing Greece into the first half of the second semi-final. Fokas Evangelinos was hired to organise the staging and choreography for the performance. However, due to the 2020 coronavirus pandemic in Europe, the contest was cancelled on 18 March 2020. The EBU announced soon after that entries intended for 2020 would not be eligible for the following year, though each broadcaster would be able to send either their 2020 representative or a new one. ERT responded that its intention was to continue its cooperation with Stefania for the next contest in 2021.
Alternative song contests
Some of the broadcasters scheduled to take part in the Eurovision Song Contest 2020 organised alternative competitions. Austria's ORF broadcast Der kleine Song Contest in April 2020, which saw every entry being assigned to one of three semi-finals. A jury consisting of ten singers that had represented Austria at Eurovision before was hired to rank each song; the best-placed entry in each semi-final advanced to the final round. In the third semi-final on 18 April, Greece placed seventh in a field of 13 participants, achieving 51 points. Greece's song also partook in Sveriges Television's in May, and was qualified for the final round, finishing 15th.
