First aired on 1 March 1970, it is currently the longest-running television programme and the second most watched national newscast in Chile.

The 9pm primetime edition is broadcast primarily live from the Channel 13 Television Centre in Providencia, Santiago Metropolitan Region to viewers all over Chile.

Teletrece was launched on 1 March 1970, replacing the former newscast El repórter Esso (1964–1968) and Martini al instante (1968–1970).

In 1983, Santis ended the May 14 newscast with a tribute to the Lira Street news studios of Channel 13, then located in the downtown Santiago campus of the Catholic University which it shared for many years, as the editions to be aired from the following day onwards would be produced and aired live from the brand new news studios at the Channel 13 Television Centre.

On 26 September 1999, Rodrigo Jordan, Canal 13 director-in-chief, relaunched the telecast with new presenters Jorge Diaz[5] and Carolina Jimenez for weekdays, and weekends by Silvia Carrasco and Rodolfo Paredes.

Regular members of the panel included Ramon Ulloa, Antonio Quinteros, and Matilde Burgos.

In 2009, Canal 13 began to centralize the newscast's reporter pool and content, closing Teletrece's news centres in Antofagasta and Temuco.

At first, the afternoon edition, then branded Teletarde, was presented by Mirella Latorre (later replaced by Gina Zuanic) and Julio Pérez, the then early evening Telenoche with Miranda, Rose Marie Graepp (later replaced by Virginia Escobedo) and Pepe Guixé, and Telecierre by Freddy Hube, who was co-presenter with Guixé and Abad in the main newscast.

Both were broadcasting from the Channel 13 Newsroom, first located at the Central Campus and then at the Television Centre, and by 1990 moved on to share a singular studio with the main edition and with half-hour durations each.
