Re: LUXEMBOURG 2019
250 000 - 300 000 already seems much TBH
Not necessary everything has to be funded by the broadcaster. For instance our broadcaster pays for the participation fee, our commercial co-broadcaster funds the NF and the winner's preparation costs (the crew's salary, the staging, plane tickets, hotel accommodation for the whole delegation for 2 weeks etc.) and the winner pays for their promo (music video, promo gigs, improvement of the song etc.).
In this particular case they won't have a co-broadcaster so everything depends of RTL which (if they're interested in participation) should search for/negotiate with investors.
The government, private business, performers themselves, RTL profits...
+ ad revenue & televoting revenue partly compensate the participation fee, performers receive additional promo & royalties for their songs.
