UniMás is available on cable and satellite television throughout most of the United States, with local stations in over 40 markets with large Hispanic and Latino populations.

[7] By September 2000, USA Broadcasting had expanded the "CityVision" entertainment format to three of its thirteen other HSN outlets – with some of the stations adopting call letters referencing common nicknames for their home cities – WHOT-TV (now WUVG-DT) in Atlanta, KSTR-TV in Dallas–Fort Worth and WHUB-TV (now WUTF-DT) in Boston.

The revamped network would feature Mexican and Colombian-imported programming from Televisa, Caracol Televisión and RTI Colombia (the latter two of which compete with RCN in the domestic Colombian market), which had maintained longstanding programming and production agreements with rival Telemundo, through contracts struck months before the relaunch, it would also increase its reliance on sports content for its weekend schedule.

[26] On May 13, 2019, UniMás refocused its programming strategy in order to target a younger audience to that of its parent network Univision, with a focus on news, sports, unscripted entertainment and reality shows, most of them broadcast live.

On that day, the network added an early edition of Noticiero Univision: Edición Nocturna at 10 p.m., coinciding with the arrival of Colombian newsreader Patricia Janiot to the broadcast, co-anchoring alongside Enrique Acevedo.

In January 2009, TeleFutura launched the daily gossip show La Tijera, hosted by Charitin Goyco, Liliana Rodriguez, Paul Bouche, Carolina Sandoval and Augusto Valverde.

[33] The hosting staff was gradually altered over its two-year run to include Tanya Charry, Raul Garcia, Anabelle Blum and Rodolfo Jimenez joining Sandoval; the show was cancelled in October 2011.

[36] However, Univision Communications chose to relinquish the rights to the two pageants on June 25 of that year, as part of its decision to cut business ties with then-Miss Universe Organization co-owner Donald Trump in response to controversial remarks he made during his June 16 speech announcing his candidacy for the Republican Party Presidential nomination in which Trump stated that Mexicans immigrating into the U.S. were responsible for the transporting of illegal drugs, brought crime, rapists and drug dealers into the country, and called for the building of a wall along the Mexico–United States border.

[37][38][39][40] The termination of the agreement led Trump and the Miss Universe Organization to jointly file a breach of contract and defamation lawsuit against Univision Communications in the New York Supreme Court on June 30, 2015, seeking $500 million in damages.

[26] On November 1, 2014, UniMás began airing rebroadcasts of the El Rey Network professional wrestling showcase Lucha Underground on Saturday afternoons.

When the network launched in 2002, TeleFutura launched three children's program blocks aimed at different audiences: "Mi Tele" ("My TV"), a two-hour animation block on weekday mornings featuring a mix of imported Spanish-language cartoons (such as Fantaghiro and El Nuevo Mundo de los Gnomos ("The New World of the Gnomes")); and two weekend morning blocks, "Toonturama", a three-hour lineup that mainly featured dubbed versions of American and European animated series as well as anime series (such as Flight Squad and Problem Child, Lost Universe, Tenchi Universe and Red Baron; Toad Patrol was an exception to the dubbing as it needed to use an English dub to fix translation issues) and a two-hour companion block that preceded it on Saturday and Sunday mornings, "Toonturama Junior", featuring programs aimed at preschoolers that fulfilled educational programming requirements defined by the Federal Communications Commission's Children's Television Act (among the programs featured on "Toonturama Junior" was Plaza Sésamo ("City Square Sesame"), Televisa and Sesame Workshop's Spanish-language adaptation of Sesame Street featuring a mix of original segments featuring characters based on its U.S.-based parent series and dubbed interstitials from the aforementioned originating program, which had aired on Univision since 1995 and passed on the U.S. television rights to TeleFutura at its launch).

[52][53] On September 9, 2018, in an agreement with Animaccord, the network launched the popular Russian cartoon Masha and the Bear, airing it every Sunday morning.

Counting only conventional over-the-air affiliates, the network has a combined national reach of 46.54% of all households in the United States (or 145,419,291 Americans with at least one television set).

Despite Univision's over-the-air expansion since its sister network launched as TeleFutura, UniMás has been slower in expanding its national coverage through broadcast television outlets and does not have over-the-air stations in several major markets with relatively sizeable populations of Hispanic and Latino residents where Univision and/or at least one of its competing Spanish language networks have broadcast affiliates, most notably Seattle, Washington; Kansas City, Missouri; Amarillo, Texas; Oklahoma City, Oklahoma; and Midland, Texas.

Since the service launched on October 29, 2012, Univision Communications' multi-platform streaming service UVideos has made full-length episodes of UniMás' programs (including those produced by Televisa and its other content providers) available on its website at UVideos.com and companion mobile app for smartphones and tablet computers supporting the iOS and Android platforms (with programs streamable over 3G and WiFi networks).

[57] The most recent episodes are usually made available for streaming on the service (as well as Univision on Demand) the day after their original broadcast to subscribers of participating pay television providers (such as Comcast, Verizon FiOS and Time Warner Cable) using an ISP account via an authenticated user login.

The service also includes select original digital content, user-enabled English subtitling for most programs (except for excerpts from Noticiero Univision broadcasts) as well as a social stream featuring viewer comments from the UVideos and other social media platforms, which are time-synched to the user's local time zone to mimic a live relay to the user as posted during the program's original broadcast.

Restrictions imposed by film studios that supply such content for the network prohibit certain movies carried on UniMás from being made available on Univision NOW.

[64][65] UniMás' master feed is transmitted in 1080i high definition, the native resolution format for Univision Communications' network television properties.

What was then TeleFutura launched its high definition simulcast feed at 12:02 a.m. Eastern and Pacific Time on January 1, 2010, on its East and West Coast flagship stations in New York City and Los Angeles, WFUT/WFTY-DT and KFTR-DT (which, along with Univision, became the last two U.S. broadcast networks to begin offering their programming in HD).

[67] Most of the network's programming is presented in HD As of October 2015[update] (including most telenovelas; sports programs, including soccer events; newsmagazines; and most feature films, depending on the availability of high-definition "television" cuts of films) is broadcast by the network in high definition; exceptions exist with certain telenovelas, sitcoms and variety series as well as select children's programs aired as part of the network's weekend morning children's block produced prior to 2008 that air in reruns, which continue to be presented in their native 4:3 standard definition format.

DirecTV began carrying the Eastern Time Zone feed of the HD simulcast nationwide on April 28, 2010;[68] Dish Network subsequently added it two weeks later on May 12, 2010.
