# 24 horas (Chilean TV program)

24 horas (English: 24 hours) is the brand that identifies the gathering and broadcasting of news in the Chilean public broadcaster Televisión Nacional de Chile. It started as an informative program of the same television network on 1 October 1990. Then in 2009, it became a television channel called Canal 24 horas.
It has four different editions: "24 Horas Tu Manana" (mornings), "24 Horas Al Dia (midday), "24 Horas central" (evening), and "24 Horas Al Cierre" (late night). National news bulletins are broadcast by TVN, Canal 24 horas, and TV Chile.

## History

Its first edition was broadcast on October 1, 1990, led by Cecilia Serrano and Bernardo de la Maza on the "Edición Central". Gradually, the editions of the newscast gained ground in the ratings on rival Canal 13, overtaking the latter in the mid-1990s. On October 10, 2001, coinciding with the première of the soap opera Amores de Mercado (Market's Lover), which preceded the news, the Central Edition scored 42.2 rating points between 21:00 and 21:56, a figure that hasn't been matched since.
On March 8, 2004, it changed its image to match the new logo of TVN. There were other major changes that year; the old presenters, Bernardo de la Maza, and Cecilia Serrano, were replaced with Amaro Gomez-Pablos and Consuelo Saavedra. This move was criticized.
Between 1999 and 2002, it had a fifth edition entitled Edición Vespertina de 24 Horas (24 Horas Evening Edition), which aired at 18:00. It was hosted by Consuelo Saavedra, Mónica Rincón, María Isabel Toloza, and later by journalist María Jesús Sáinz.
Local newscasts are issued at 14:20 and 21:35.
In 2002, the newsletter closed the signal transmitted by the Santiago Metro, called MetroTV. In 2005, she returned to the United States, the journalist Consuelo Saavedra, and assumed the leadership of the main news with Amaro Gómez-Pablos. One of the highlights of the news was its live coverage of the Iraq War and especially the fall of Saddam Hussein, featuring Santiago Pavlovic, Rafael Cavada and cinematographer Alejandro Leal.
In October 2007, 24 Horas started a channel on YouTube, making Televisión Nacional de Chile the first television station in the country with an official presence on the site.
On August 1, 2008, VTR announced that by the end of the year, it will air TVN 24 Horas, a 24-hour news channel that rivals the local branch U.S. news network CNN Chile (which premiered on December 4). The new channel launched in March 2009, becoming the second uninterrupted news channel in the country after CNN Chile, which was launched in December 2008. It was launched with the objective of becoming the definitive news source in the country. Air time is divided into different thematic segments, covering economic, international, sports, local issues, entertainment, and technology, and it broadcasts the three main news programs of TVN. For its international content, it has an alliance with the U.S. MSNBC. After its inauguration, the channel's first long-term coverage was the aftermath of the 2010 Chilean earthquake in the south-central zone of Chile from February 2010.
