Televisión Federal S.A., best known as Telefe and later as TLF, is an Argentine television network. Formerly known as Canal Once (Channel 11), a state-run network, it was privatised and established as Telefe in 1989, when Grupo Atlántida (80%) and News Corporation (20%) took over the channel. Since 1997, it is owned by Telefónica.
Under the command of Gustavo Yankelevich, the network became the most watched channel in Argentina and has been number 1 in ratings ever since 1990 (during some years, in a very close battle with El Trece). Yankelevich stayed on the channel until 2000 and was replaced by Claudio Villarruel. Villarruel leaded the channel until 2009 and was replaced by Marisa Abadia. Finally, Tomás Yankelevich, Gustavo and Cris Morena's son, was hired to lead the channel from 2011 and is the current director.
The channel runs mostly local productions but there are a few exceptions: The Simpsons is aired since 1991 with huge ratings; during the 1990s, El Chavo and American sitcom The Nanny were also enormously popular; Brazilian, Mexican and Colombian telenovelas are also aired in afternoon slots. Until 2001, most of the shows were produced in-house but since the Argentine crisis of that year independent production have become more usual, although the channel still co-produces most programs.
Iconic shows during Yankelevich's period include Videomatch, Grande, Pa, Hola Susana/Susana Giménez, Brigada Cola, Amigos son los Amigos, Verano del 98, Chiquititas, Muñeca Brava, Perla Negra, Jugate Conmigo, Naranja y Media and Ritmo de la Noche, among others.
During Villarruel's period, iconic shows include Resistiré, Montecristo, Los Roldán, Vidas Robadas, Los exitosos Pells, Los Simuladores, Casi Ángeles, Hermanos y Detectives, Amor en Custodia and highly successful local remakes of US sitcoms including Casados con Hijos and La Niñera. The station is also responsible for the five editions of the Argentine version of Big Brother (Gran Hermano) and three of Star Academy (Operación Triunfo).
Also, due to the success of the adaptation of the sitcom The Nanny, other famous American sitcoms such as Who's the Boss? and Married... with Children have been localized. The last production Aquí no hay quien viva is a local adaptation from the Spanish sitcom of the same name.
In 2010 and 2011, Telefe lost out for Canal 13 for the first time. It recaptured the top spot in 2012, thanks in part to the huge success of Graduados and Dulce Amor. It's main star is Susana Gimenez and the host Marley.
Production companies that work exclusively for Telefe include Cris Morena Group (since 2006), Underground Contenidos (since 2008) and RGB Entertainment (since 2006). The channel also does lots of co-productions with Endemol. Until 2004, Tinelli-owned Ideas del Sur also produced exclusively for Telefe but now moved to El Trece and Cuatro Cabezas produced from 2004 to 2008.
In 1998, the channel introduced a new version for the viewers in North America and other countries around the world. This is called Telefe International (Telefe Internacional in Spanish). The channel has the same shows and along with that, it also includes some new changes in the logo design. From 1998 to 2011, the logo adds an oval but later retains the same design after that.
