As the Spanish International Network (SIN),
KMEX began broadcasting news programs on June 1, 1981, when the network debuted a weeknight newscast,
Noticiero Nacional SIN ("SIN National News"), which originally aired as a single half-hour broadcast each weeknight at 6:30 p.m.
Eastern Time. Guillermo Restrepo served as the newscast's first anchor and was later joined by Teresa Abate (later Teresa Rodriguez) - the latter of whom became the first Hispanic female anchor of a national newscast in the United States. In 1987, after Spanish International Network co-founder Emilio Nicolas Sr. and
Emilio Azcárraga Milmo (co-owner of
Mexican broadcaster
Televisa, who assumed part-ownership of SIN from his father
Emilio Azcárraga Vidaurreta in 1972) sold their interests in parent company Spanish International Communications to
Hallmark Cards after the
Federal Communications Commission (FCC) and the
U.S. Justice Department asked them to divest the network to a U.S.-based company amid inquiries into Nicolas' use by the Azcárraga family to skirt agency rules prohibiting foreign ownership of broadcast media outlets, In 1987, the network – which was renamed Univision following the purchase – appointed former
NBC News producer Roberto FE Soto to produce a revamped flagship evening newscast,
Noticiero Univision. Mexican-born journalist
Jorge Ramos – who joined SIN in 1984 as a reporter for KMEX and later host of the network's first
morning program,
Mundo Latino – was reassigned and paired alongside veteran KMEX journalist
María Elena Salinas – who replaced Teresa Rodriguez as anchor – to co-anchor the evening newscast. In the summer of 2004, Telemundo signed María Antonieta Collins – who had been anchor of the weekend editions of
Noticiero Univision – to a long-term contract to host a morning news and lifestyle program for the network,
Cada Dia with Maria Antonieta ("Every Day with Maria Antonieta") (Collins would return to Noticias Univision as a senior special correspondent in 2011). On October 24, 2005,
Edna Schmidt – then the national news anchor of the
Noticias al Minuto newsbriefs on sister network TeleFutura (now
UniMás) – was named as Collins' replacement as co-anchor of the weekend newscasts, joining Urquidi on the early evening edition. On February 28, 2009, Univision terminated the contracts of Enrique Gratas and Sergio Urquidi as part of corporate cutbacks enacted by parent company
Univision Communications spurred by the
Great Recession and a sharp downturn in advertising spending, which resulted in the layoffs of 300 employees (or 6% of its workforce), as well as the cancellation of the weekend editions of the newsmagazine
Primer Impacto and its companion program
Primer Impacto Extra. The late-night edition retained the
Ultima Hora brand, though restoring a more traditional newscast format. On May 29, 2009, Enrique Teuteló – then the 11:00 p.m. anchor at Univision's
Miami owned-and-operated station WLTV-DT – was named as Urquidi's replacement on the weekend editions of
Última Hora and
Noticiero Univision: Fin de Semana. On March 3, 2011, Univision correspondent
Martin Berlanga announced while substituting during that evening's edition of
Ultima Hora that he would taking over as weekend anchor, replacing Enrique Teuteló, who was terminated by the news division the day prior (he would subsequently become morning co-anchor at the network's
New York City owned-and-operated station WXTV-DT that June). Then on March 7, the network announced that
Ilia Calderón would be named anchor of the late evening edition, which was retitled to its original name
Noticiero Univision: Edición Nocturna, while retaining her duties as co-anchor of
Primer Impacto. After a brief sabbatical from the weekend editions, Edna Schmidt was subsequently reassigned to weeknight co-anchor of the late newscast, before being let go by Noticias Univision after 19 years with the network on September 11, 2011, while in New York City to cover the ceremonies in remembrance of the 10th anniversary of the
September 11 attacks. On January 10, 2012, Univision removed Berlanga from his duties as anchor of the weekend newscasts after only ten months, effective after the January 15 edition of
Fin de Semana, in which Berlanga did not indicate he would no longer anchor the weekend broadcasts; he was reassigned to a correspondent role, before Berlanga departed from the network after 17 years in March.
¡Despierta América! news co-anchor
Félix de Bedout and longtime
Televisa anchor/correspondent Lourdes Ramos (sister of main anchor Jorge Ramos) were concurrently named as his replacements; originally slated to start together on January 21, de Bedout debuted that week as solo anchor of the Saturday and Sunday editions, with Ramos joining him on the following week on January 28. On January 23, 2012, the program introduced a new graphics package; it also relocated production of
Noticiero Univision and
Edición Nocturna to a new set branded as "[el] Centro de Noticias" ("[the] News Center"). The set was later updated to incorporate the new version of Univision's universal corporate logo, which debuted on January 1, 2013. On April 23, 2012, former Telemundo anchor and special correspondent
Enrique Acevedo joined Univision as a co-anchor of
Noticiero Univision: Edición Nocturna (at which time, the late editions of the weekend broadcasts adopted that same title), alongside Ilia Calderón. In September 2012, Univision began to timeshift the Saturday early-evening editions of
Noticiero Univision: Fin de Semana one hour earlier in the
Eastern,
Central and
Mountain Time Zones (at 5:30 p.m. Eastern and 4:30 p.m. in the other two) since 2012, following the addition of
soccer matches that precede Univision's prime time variety programming, on weeks in which those matches are scheduled to air within the newscast's regular 6:30/5:30 timeslot. On October 1, 2012, the
Academy of Television Arts and Sciences honored main anchors Jorge Ramos and Maria Elena Salinas with
Lifetime Achievement Awards at the
33rd News & Documentary Emmy Awards for their journalistic work with
Noticiero Univision and its parent news division. In September 2013, Univision moved production of its evening newscasts to the Univision NewsPort, based in a converted former office and warehouse complex near Univision's network headquarters in the
Miami exurb of
Doral, Florida that would also house the operations of
Fusion, Univision's
cable news venture with
ABC News. The NewsPort houses five studios and five
control rooms, one of which – located directly next to the newsroom offices – began housing the "Centro de Noticias" set in February 2015, following completion of the set's reassembly in the NewsPort building; all
Noticias Univision broadcasts were conducted from the newsroom in the interim. On July 14, 2014, Lourdes Ramos stepped down as weekend co-anchor to relocate to
Madrid with her husband, although she would remain with Noticias Univision as a special correspondent. On September 3, 2014, Noticias Univision announced that Arantxa Loizaga (who joined the network in 2007 from
San Antonio owned-and-operated station
KWEX-DT, where she served as anchor of its 10:00 p.m. newscast and co-host of the community affairs magazine program,
Portada San Antonio) would become co-anchor of
Noticiero Univision: Fin de Semana, effective Saturday, September 6. In February 2021, Loizaga resigned from her position after being hired by Univision's competitor
Telemundo, where she would host their new morning show,
Hoy Día. On December 8, 2017, Maria Elena Salinas stepped down as weekday anchor and departed Univision after 36 years with the network to focus on being an independent news producer with Ilia Calderón being named as co-anchor to the weekday newscasts with Jorge Ramos. Subsequently, Patricia Janiot joined Univision on January 29, 2018 to anchor
Edición Nocturna after departing her previous position at
