Preparations for the organisation of the 2020 contest began on 19 May 2019, immediately after the Netherlands won the 2019 contest in Tel Aviv, Israel. Jon Ola Sand, the executive supervisor of the European Broadcasting Union (EBU) for the contest, handed AVROTROS, the Dutch broadcaster participating in the contest, a stack of documents and a USB drive with tools to begin the work needed to host the next contest. AVROTROS is set to co-produce the event with sister news broadcaster Nederlandse Omroep Stichting (NOS) and their parent public broadcasting organisation, Nederlandse Publieke Omroep (NPO), each assuming a different role in the production.
According to Mark Rutte, the Prime Minister of the Netherlands, several mayors had already started bids on behalf of their municipalities, lobbying him through text messages, within hours of Laurence's win. The following cities have expressed interest in bidding:
Eligibility for potential participation in the Eurovision Song Contest requires a national broadcaster with active EBU membership that will be able to broadcast the contest via the Eurovision network. The EBU will issue an invitation of participation in the contest to all active members. In contrast to previous years, associate member Australia will not need an invitation for the 2020 contest, as it was granted permission to participate until 2023.
The following countries participated in the 2019 contest, but have not yet announced whether they would participate in the 2020 contest:
Andorra – In March 2019, Andorran broadcaster Ràdio i Televisió d'Andorra (RTVA) stated that they would be open to co-operating with Catalan broadcaster TV3 to participate in future contests. The two broadcasters had previously co-operated when Andorra debuted in the 2004 contest.
Bosnia and Herzegovina – On 28 December 2018, Bosnia and Herzegovina's head of delegation, Lejla Babović, stated that returning to the contest was their primary goal, but their financial situation, debt with the EBU and lack of funding would make it difficult for the country to return in 2020.
Bulgaria – On 8 April 2019, Bulgarian broadcaster Bulgarian National Television (BNT) stated that they had no plans to return to the contest in the near future, citing how the contest no longer fit the broadcaster's content strategy.
Israel – On 9 May 2019, Israeli broadcaster KAN confirmed that HaKokhav HaBa, the talent show that was used to select Eurovision Song Contest participants in the past, would return for another season. However, it was not confirmed whether it would be used to select Israel's participant for 2020.
Malta – On 20 January 2019, it was confirmed that the talent show X Factor Malta, with which the participant of the 2019 contest was selected, would return for a second season in 2020. However, it was not confirmed whether it would be used to select Malta's participant for 2020.
Spain – On 15 January 2019, the director of Spanish broadcaster RTVE, Eladio Jareño, confirmed that talent show Operación Triunfo would make a return in 2020. Even though it was used as the selection process for Spain in 2018 and 2019, it is not confirmed that Spain will use it once again for selecting their Eurovision 2020 entry.
Turkey – In August 2018, İbrahim Eren, the general manager of Turkish broadcaster Turkish Radio and Television Corporation (TRT), explained that they could not broadcast a show that contained sexually ambigous people (referencing Conchita Wurst, the winner of the 2014 contest) at times when children were still watching television. He also commented that the EBU had deviated from its values due to its executives, and that the broadcaster disagreed with the split jury/tele-voting system, which was introduced in 2009.
Associate EBU members
Kazakhstan – On 22 November 2018, Jon Ola Sand, the executive supervisor of the contest, stated that Kazakhstan's participation in the contest needed to be discussed by the contest's reference group. Kazakhstan had previously been invited to participate in the Junior Eurovision Song Contest 2018 by that contest's reference group, though that would have no effect on their participation in the main contest.
Catalonia – In late 2018, Catalan broadcaster TV3 received permission from the Catalan Parliament to push for EBU membership. Although Catalonia is part of Spain, the EBU is evaluating the broadcaster's membership request; approval would allow TV3 to debut in the 2020 contest.
Faroe Islands – In late 2018, Faroese broadcaster Kringvarp Føroya (KvF) showed interest in joining the EBU and participating in the contest. According to the EBU, they are not excluded by the rule that only independent nations can join, and as a result KvF started internal discussions on applying for the EBU membership, participating in the contest, and hosting a national final similar to the Dansk Melodi Grand Prix in Denmark.
Kosovo – Mentor Shala, the general director of Kosovar broadcaster Radio Television of Kosovo (RTK), stated that the broadcaster was still pushing for full EBU membership, and that it hoped to debut at the 2020 contest. RTK is in talks with the EBU regarding the membership. The EBU is set to vote on full membership of RTK in June 2019; approval would allow the broadcaster to debut in the 2020 contest or shortly after that.
