Página 12 (sometimes stylised as Pagina/12, Pagina|12 or Pagina12) is a newspaper published in Buenos Aires, Argentina. It was founded on 25 May 1987 by journalist Jorge Lanata and writers Osvaldo Soriano and Alberto Elizalde Leal. Since 2016 the newspaper is property of Grupo Octubre, a multimedia company created by Víctor Santa María, president of the Justicialist Party in the Buenos Aires. His first president was businessman Fernando Sokolowicz, in 1994 Grupo Clarín supposedly owned a share; Lanata claimed in a 2007 interview that businessman Rudy Ulloa (a businessman close to former President Néstor Kirchner) also owned a share. The publishers also distribute a supplement covering Rosario area news, Rosario 12, since 1991. According to in house surveys, 58% of the newspaper readership is between 18 and 52 years old and belong to the medium and medium high socio economic groups: AB and C1/C2 The name of the paper comes from the fact that its preliminary editions as it was being developed had 12 pages. The name had already been chosen, thus the publishers opted to reserve the twelfth page for reports or news stories of central importance. Another version holds that the paper was going to be called "Reporter" but when the owners went to register the name, they were told that the name was taken. They then decided to count the number of pages in order to choose a name. With a stark design, a daily circulation of 10,000 copies and a size of 16 pages that doubled within a few weeks, the paper was a sharp contrast with other Argentinian newspapers due to its progressive orientation, its in-depth articles (each one occupying more than a page on average) and rich analysis. Inspired by the French paper Libération, its style contrasted with the conventional Argentine press, where a higher priority was placed on showcasing a wide variety of information as opposed to more probing reports.
