On 1 January 1978, Teletrece made the first national colour news broadcast, this after the Pinochet government decree exempted the color television as "prohibited 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.
