Las Noticias Teleonce (1986-2002)

News programming on WLII began in May 1986, with Ramón Enrique Torres and Jennifer Wolff as anchors of the 5:00 p.m. newscast. In 1990, a noon newscast premiered with Torres and Margarita Aponte as its anchors, followed by the 10:30 p.m. newscast with Torres. On March 11, 1991, a weekday morning news program, Tu Mañana, made its debut; the program was anchored by Carlos Ochoteco and Cyd Marie Fleming and featured segments such as panels of experts on different topics.

Over the years, many people worked on Tu Mañana and Las Noticias. Reporters such as Carmen Dominicci, Elwood Cruz, Susan Soltero, Bruni Torres, Nuria Sebazco, Rommy Segarra, Felipe Gómez (now at WAPA-TV), Ada Monzón (now at WAPA-TV), and Liza Lugo have been featured.

In 1996, a monthly investigative/tabloid newsmagazine called Las Noticias Xtra began airing, which offered reports considered to be shocking by audiences. Taboo themes in Puerto Rican society such as homosexuality were featured. Las Noticias Xtra eventually was reduced to a weekly segment seen during the 6:00 and 11:00 p.m. newscasts. During WLII's TeleOnce years, the station's slogan was "TeleOnce: 24 horas el canal de Las Noticias" (lit. 'TeleOnce, the 24-hour news channel'), paralleling the 24-hour news source trend in the United States at the time.

Las Noticias Univision (2002-2014)

After the Univision integration in 2002, Las Noticias became Las Noticias Univision and acquired the branding of all other Univision O&O stations news broadcasts. WLII began broadcasting its local newscasts in high definition on September 26, 2010. Due to budget cuts that were imposed by Univision in Miami, WLII reduced its news department by between 20 and 50 employees, and Las Noticias a las 6 was reduced from 60 to 30 minutes. The station discontinued its weekend newscasts on January 5, 2014;^[1] following this, it reduced its news operation from 35+1⁄2 to 32+1⁄2 hours each week, which led to the firing of 19 employees.

On October 17, 2014, Univision announced that Jaime Bauzá had been promoted to senior vice-president and general manager of all of the network's operations in Puerto Rico. The first change he made was the firing of 109 employees. This caused the closing of the entire news department, including reporters, anchors, and cameramen. On that day, the morning show Tu Mañana was shown as normal, but the midday show Tu Mediodia was not, during which time reporter Daisy Sánchez published on her Twitter account the announcement of the news department's closing.^{[2][3][4][5][6]}

The roundtable talk show Rubén & Co. replaced the 5:00 p.m. spot left by Las Noticias. The show was extended from 30 to 60 minutes, and filled the 5:00 p.m. timeslot until its cancellation on January 20, 2016.^[7]
