On 11 September 1973 after the coup d'état in the morning, Televisión Nacional did not start broadcasting during the day and the studios were closed for three days, there was also an assault on the headquarters, where abundant amounts of audiovisual material were burned by the military, ending with a large part of the records of the first years of broadcast. During the three days it was closed, Canal 13 decided to occupy the TVN national network, because it was the only one authorized to broadcast after the coup d'état. After resuming the broadcast, it becomes the official television media of the new military dictatorship with informative management and strong control in the programming, granting advantage in audiences to Canal 13 news programme Teletrece, which was considered "more liberal".
