Her departure from Antena 3 after 11 years coincided with a process of restructuring the network, which involved layoffs, although she left weeks before they began, after not finding a show to join.

[2] In 2009 Viza returned to television, briefly joining the regional station Aragón TV and contributing to the TVE Catalonia [es] program Vespre a la 2.
