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 by then 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.
