LT 83 TV received its federal license in August 1964 and signed on June 20, 1965, some years after shareholders exploited the foundation of a television station.

The station also produced such important local programming as the matches held in Rosario during the 1978 FIFA World Cup and Pope John Paul II's visit to the city in 1987.

In 2015, after the death of owner Alberto Casiano Gollán, a 55% share in Televisión Litoral, the license holder, was sold to local businessmen associated with the Fundación Libertad group, for around US$13 million.

Channel 3 holds an affiliation with Artear's El Trece and primarily airs its national programs.

The local news on El Tres tends to focus specifically on the Rosario metropolitan area, with little if any coverage of southern Santa Fe province or the cities where repeaters are located.
