Teletrece was launched on 1 March 1970, replacing the former newscast
El repórter Esso (1964–1968) and
Martini al instante (1968–1970). It is the current flagship programme from the news division of the network, which started in 1963. On 9 November 2005, Teletrece adopted
closed captions (
CC). In mid-2007, Teletrece began to be produced in
high definition. In 2009, Canal 13 began to centralize the newscast's reporter pool and content, closing ''Teletrece's'' news centres in Antofagasta and Temuco. The channel, later on 29 August 2014, briefly closed the news centre in
Concepción, leaving only the news centre of Valparaiso, but the decision was rescinded. Since 22 October 2014, the bulletin has been simulcast on the 13c channel. On 16 March 2016, Teletrece debuted a new graphics package and minor updates to the set.
Afternoon and late-night editions These editions,
Teletrece Tarde and
Teletrece Noche, began in 1970, the same year as Teletrece, whose 9 pm edition is considered the main primetime edition (
edicion central), together with the 11:30 pm
Telecierre, these ended in 1973–1974 (with the departure of some of its presenters) and would return in 1981, remaining on air until the present. 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.
Telenoche was replaced in 1974 with the newscast
24 Horas (not to be confused with the same-named newscast on TVN), which was short-lived, it was presented by Julio López Blanco, who left for TVN in 1975. Both
Teletarde and
Telenoche returned to broadcasts in 1981 with 20-minute broadcasts and their new presenters Cecilia Serrano and Jorge Diaz, with the latter now taking over
Telecierre's old timeslot. Serrano left the afternoon newscast for TVN in 1990, with the then
Teletrece weather presenter Jeannette Frazier replacing her while Diaz was, upon his promotion as presenter for weekends, replaced by Loreto Delpín. 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. == Presenters ==
