goods status it had since January 1972 under a strengthening of protectionist policies during the period 1970 to 1973. In 1977, Javier Miranda joined Teletrece as alternate principal presenter for weekends, leading up to its credibility strengthened against competitors in that timeslot, including the national newscast 60 minutos (TVN), criticized by opponents of Augusto Pinochet to be partial and lacking in credibility. The Miranda-Santis tandem would prove to be pivotal as the newscast soon became the nation's most watched and most trusted. Each of the two presenters, joined by a variety of segment panel presenters within their respective airings, gave the newscast the feel and look of a more advanced news program. In 1983 Santis ended the May 14 newscast with a tribute to the legendary Lira Street news studios of Channel 13, then located in the downtown Santiago campus of the Catholic University which it shared for many years, in a stunning farewell, 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. In 1985 it was the first newscast reporting on the consequences of 1985 earthquake on the south coasts of Valparaíso Region, which left 177 dead. Teletrece then continued until about 1 AM broadcasting what would be one of its marathon editions in its history. In 1988, Santis left to join the TVN news department, leaving Miranda as the presenter for weekdays. Augusto Gatica then assumed the presenter role for weekends until 1990, when he was replaced by Jorge Díaz. Since Miranda, too, was the presenter of the Tuesday night variety programme Martes 13 until he left the series following the 1992 season, Gatica also became relief presenter for the Tuesday edition until 1989, when Diaz took over. In 1990, Teletrece became a single-presenter program, which moved to the Channel 13 Press Center studios. In 1998 the morning edition was launched, which in 1999 restarted broadcasts under the brand Teletrece AM. On Sunday 26 September 1999, Rodrigo Jordan, Canal 13 director-in-chief, relaunched the telecast with new presenters Jorge Diaz, 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. All Teletrece editions, studios and graphics were refreshed to be more cohesive with the new branding. When Diaz left the program in 2002,
