The Catalan public television channel is called TV3. This TV channel organizes every year a telethon (a TV event/program through which they raise money for a worthy cause) which is called La Marató de TV3.
The purpose of La Marató is to raise funds for scientific research into diseases that are currently incurable and to inform society about these diseases. Everything is done with the TV program usually aired the Sunday before Christmas and lasts 15h, while around Catalonia many companies, entities, and towns organize different activities to raise money. There is also a music CD released with the collaboration of many artists before the program is aired.
It is a very successful event celebrated yearly since 1992. This year is about mental health. And the year when they raised more funds was in 2018 with 15.068.252 € raised to battle cancer.
