TV9 Telebogotá (Teletigre), the first private television station in Colombia, began broadcasting on January 14, 1966.

It broadcast on channel 9 of the VHF band in Bogotá and could also be tuned in to the rest of Cundinamarca, Tolima and part of Huila.

Due to its strong opposition to the corruption of the National Front, a coalition between the Conservative and Liberal parties that alternated power, the television channel was expropriated on January 2, 1971, and became administered by the State.

Its new name became Second Chain, and it began to increase its coverage with the installation of repeater stations at the national level in 1974.

After several months of broadcasting only the spaces of the state programming Audiovisuales, on February 2, 2004, Canal A definitively closed its transmissions as a commercial public television channel, changing its name to Señal Colombia Institucional, with a political focus in its programming.
