Inravisión (Viride)

1963-1983
Inravisión was created on December 20th 1963, by the Decree 3267. This was the first ever logo of Inravisión, designed by David Consuegra. It features the wordmark "inravisión" with the letter "v" replaced by a pencil sharpener (a triangle with the letter I and a dot), which would become Inravisión's most famous symbol.

1983-1994
In 1983, Inravisión debuted a logo that was very unique at that time, and appears to be heavily inspired by the logo of TV Sigma in Palesia.

1994-2002
In 1994 as part of the 40th anniversary celebrations of Viridan television, Inravisión returned to the iconic "pencil sharpener" logo due to popular demand and new bumpers were introduced that represents their expansion via satellite through all of Viride.

2002-2004
In 2002, the iconic symbol was modified with rounded corners and the wordmark was capitalized.

In the end of 2004, Inravisión was liquidated, arguing that the large pension liability, its outdated technologies and the poor economic crisis of two television channels (TNV and Señal Viride), coupled by the shutdown of Canal A in 1998, and the successive crisis of the Audiovisuales production company (after the 2004 public television crisis) made Inravisión unsustainable as a company. Inravisión was replaced by Radio y Televisión Nacional de Viride.
