On December 9, 1963, through Decree 1337, the National Executive Branch awarded Compañía de Radio y Televisión S.A. (at that time in the process of formation and made up of 15 people) a license to exploit the frequency of channel 11 in the city of Salta, capital of the province of the same name.

[4] On December 1 of that same year, the channel's repeater was inaugurated in Rosario de la Frontera,[5] while on March 1, 1981, the relay station located in Tartagal began its operation.

[10] In 1989, Televisión Federal S.A. won the license for the privatization of channel 11 in Buenos Aires; one of the shareholders, Televisoras Provinciales, was a consortium of interior television stations, including Emisora Arenales.

[11][12] Atlántida Comunicaciones acquired Televisoras Provinciales's share in Telefe in April 1998, as well as seven of the network's 10 affiliated stations, including LW 82 TV;[13][14] the purchase was consummated that September.

[18] On 30 November 1999, Spanish communications company Telefónica announced that it would purchase the 70 percent of Atlántida it did not own, including Telefe, seven affiliates, and radio station FM Hit, in a transaction valued at US$530 million.

On 19 April 2000, the Secretariat of the Defense of Competition and the Consumer, Argentina's antitrust regulator, approved both transactions, contingent on the sale of one of the two Mar del Plata television stations within 180 days.
