canal once (formerly once and once tv) is a Mexican educational broadcast television network owned by National Polytechnic Institute.

The network also operates an international feed which is available in the United States and Venezuela via satellite from DirecTV and CANTV, via online from VEMOX, VIVOplay and also on various cable outlets, on "Latino" or "Spanish" tiers.

[1][2] Its first broadcast was a mathematics class transmitted from a small television studio located at the Casco de Santo Tomás, in the northern part of Mexico City.

[1] In 1969, Canal Once was the first Mexico City TV station to relocate its transmitter to Cerro del Chiquihuite, in order to improve its signal.

The IPN built transmitters in cities such as Cuernavaca and Tijuana in the late 1990s, and in the 2000s and early 2010s, it expanded to build in the states of Sinaloa, Durango and Chihuahua.

[4][5] On January 23, 2019, President Andrés Manuel López Obrador nominated senator José Antonio Álvarez Lima to serve as the new director of Canal Once.

[9] He was replaced by 25-year-old Carlos Brito Lavalle, the youngest director in the station's history, who had previously helped coordinate the Aprende en Casa program and held other posts.

Some commercial stations in markets without public television air some Canal Once programming, notably XEJ-TDT in Ciudad Juárez and XEFE-TDT in Nuevo Laredo.
