During the 1990s, Morena, alongside Nilson, was responsible for the music in most Telefe's shows, including "Brigada Cola", "Ritmo de la Noche", "Videomatch", "Cebollitas" (97–98) and "Dibu: Mi Família es un Dibujo" and also for all Telefe's advertising campaigns and jingles. Before she started writing music for her own youth-oriented shows, she was, alongside Carlos "Rocky" Nilson, responsible for the music in Flavia Palmiero's children show. Morena and Nilson are the composers who made the most money in SADAIC's (Argentina's songwriters association) history. She and Carlos Nilson parted ways in 2007 when he went to work at Ideas del Sur.
