Canal 9's broadcasts began on April 18, 1983, cwhen it was inaugurated at a house at Arequipa Avenue, in the district of San Isidro by the president of the time, Fernando Belaúnde Terry, and by the archbishop of Lima of the time, Juan Landazuri Ricketts who blessed the new channel after a large advertising campaign and broadcasting a test signal for three months.

Canal 9 quickly gained audience and popularity,[3] showing during its initial decade a varied schedule consisting of feature films (after the opening ceremony it aired American Graffiti), first-run American series such as MacGyver or Hunter; successful Venezuelan telenovelas such as Las Amazonas, Cristal or La dama de rosa and animated series such as Sandybelle, The Flintstones, The Jetsons y Dungeons & Dragons.

[4] On January 14, 1992, due to the interconnection via satellite at the national level, the then denominated Channel 9 changes its name to ATV (abbreviation of Andina de Televisión).

In November 2006, the Peruvian Minister of Transports and Communications published in Peru's official newspaper "El Peruano" a decree concerning Digital terrestrial television.

ATV's HD signal was officially released on March 31, 2010, 1 day after TV Perú, being the first Peruvian private television network to do that.
