Todo Noticias (also known by its acronym TN) is an Argentine streaming and subscription television channel belonging to Grupo Clarín and operated by its subsidiary Arte Radiotelevisivo Argentino.
Oriented to the treatment of current affairs, its programming is based on permanent newscasts, although it has varied programming of general interest such as music, technology, politics, sports, stories, research, economics, shows, and others.
TN began its broadcasts on Tuesday, June 1, 1993, at 07:00, with journalists Luis Otero and Silvia Martínez as conductors. A well-known anecdote is a fact that it should not have been they who started the transmissions, but journalists Mario Mazzone and Mercedes Martí, who were "blind" after a light test before going on the air and could not comply with the objective.
In TN's first year, the Telenoche newscast broadcast in a duplex with Channel 13, the transmissions began at 07:00 and ended at 01:00. In 1994 they began to broadcast programming 24 hours a day.
TN was the first Argentine channel to broadcast live and direct from the Malvinas Islands in 1994 with Mónica Cahen D'Anvers,  and from the Marambio Base in 1996, with Mario Markic in Argentine Antarctica.
In April 1996, it changed its logo and screen design for the first time, beginning to use the logo that would make it recognized. In 1998, he changed the graphics on the screen, keeping the logo. On-screen graphics were revamped for the third time in 2001, retouching the now-classic TN logo. A TN classic that they have maintained since the beginning is Titles, the summary of the most important news of the day, which takes place throughout the day every half hour.
Since 1998, TN has had its website, where you can find videos of the news and live broadcasts (from 1998 to 2002 the address was tn.com.ar; from 2002 to 2007, TN's web address was tn24horas.com. ar and from 2007 onwards there were 6 versions of tn.com.ar). In mid-2009, the website was changed to one with a digital newspaper format, with TN videos. The website was redesigned in May 2011.
