In January 1960, the Television Department was established, and Juan Ángel Torti was appointed as its director to officially organize the station.

[6] The test transmissions ended on Saturday, April 15, 1961, at 6:00 p.m., when the Catholic University’s television station began its official broadcasts on channel 13.

Four days later, at 11:45 p.m. on December 31, 1965, the channel broadcast its first program recorded on videotape: a musical presentation by Marianela and Los Gatos, along with a greeting from Eduardo Tironi, the station director.

In October of that year, it received new mobile transmission equipment, including a videotape system, which enabled the recording of outdoor scenes.

[19] On August 9, 1968, the channel received its first satellite transmission, corresponding to a live broadcast from the Chilean Embassy in Washington D.C., to mark the inauguration of the Longovilo earth station.

It also retransmitted its programs on a delayed basis to La Serena and Coquimbo after signing an agreement with Canal 8 UCV Televisión in 1975.

[24] In December 1976, the channel signed an agreement with the Universidad del Norte Television Network, allowing it to retransmit its programs in Antofagasta, Arica, Calama, Chuquicamata, Iquique, María Elena, and Tocopilla.

This new direction was symbolized by programs created by director Gonzalo Bertrán and presenter César Antonio Santis, who joined from National Television in 1976.

They first produced musical specials featuring foreign artists and later created two-hour variety shows, starting with Esta noche fiesta in 1977.

On December 2 of that year, Canal 13, TVN, and the channels of the University of Chile and the Pontificia Universidad Católica de Valparaíso organized and broadcast the OTI Song Festival at the Municipal Theater of Santiago.

[29] From April 1 to 5, it broadcast Pope John Paul II's visit to Chile live as the official channel, at the request of the Chilean episcopate, and was the only station to cover the entire event.

This broadcast was directed by Gonzalo Bertrán and presented by Pedro Carcuro, Sergio Livingstone (for TVN), Alberto Fouillioux, and Julio Martínez (for Channel 13).

Additionally, on December 26, Sábado Gigante was broadcast for the last time from Santiago; the program subsequently moved to the Univision network in the United States.

That same year, Punta Arenas began to be broadcast in Compressed Digital Image format via satellite from the channel's Press Department.

On May 1, 1995, the press department underwent a renewal, with Javier Miranda taking over Teletrece, Eduardo Riveros heading Teletarde, and Jorge Díaz Saenger or Loreto Delpin in Telenoche.

On April 24, Channel 13 broadcast the Qualifiers for France '98, covering the Chilean soccer team's away matches against Venezuela, Argentina, and Ecuador.

In 1997, the channel began broadcasting 24 hours a day on weekends and premiered telenovelas such as Adrenalina, Playa Salvaje, Marparaíso, and Fuera de Control.

After Ducci's resignation, Jorge Herrera, the president of the Corporation's Advisory Council, assumed the role of executive director on an interim basis.

In April, the new rector of the Pontifical Catholic University of Chile, Ignacio Sánchez, appointed Marcelo von Chrismar Werth as the new Executive Director.

This restructuring occurred amid a climate of crisis within the channel due to low viewership, increased financial losses, and the failure of many new programs.
