Telenica and Televicentro, members of the Organización de Televisión Iberoamericana (OTI), were responsible for the Nicaraguan participation.

[1] According to the initial rules of the song contest, after their win, they were supposed to host the OTI Festival 1978 in Managua, but that year marked the beginning of the Nicaraguan Revolution which ended in a civil war that killed many people and destroyed completely the country.

They returned to the competition in 1980 selecting big names such as Carlos Mejía Godoy y los de Palancagüina, but the Nicaraguan results were not very successful until 1990.

In the edition of 1990, which was held in Las Vegas, Katia Cardenal got a second place for her country with the song "Dame tu corazón".

Nicaragua, just like Mexico, Chile, Guatemala and later Cuba, held a national final which was annually organised both by Telenica and Televicentro.
