The European Broadcasting Union (EBU) is looking for support for Eurovision itself and three subsidiary events – the annual Junior Eurovision Song Contest, and the Eurovision Young Dancers and Eurovision Young Musicians contests, which are held in alternating years.
There are four lots – management of comms and press relationships; management of online and commercial activities; management of online logistics tools and providing support for Eurovision's online presence.
Requests for information should reach the EBU by 16 November, and shortlisted bidders present to the EBU in early January, with chosen agencies announced at the end of the month.
Bidders are expected to work in English, with other language skills a plus. The EBU is based in Geneva and has 73 member broadcasters in 56 countries.
EBU head of live events Jon Ola Sand said: "Between them these fun, engaging shows reach more than 200 million TV viewers across the globe and more online. The EBU is looking forward to working with the most talented, creative people in Europe to take these already successful brands to a whole new level."
