Public license informationProfile

KTDO, virtual channel 48 (UHF digital channel 47), is a Telemundo owned-and-operated television station serving El Paso, Texas, United States that is licensed to Las Cruces, New Mexico. The station is owned by the NBC Owned Television Stations subsidiary of NBCUniversal (itself a subsidiary of Comcast, which also owns the local cable system in Las Cruces). KTDO's studios are located on North Mesa Street/Highway 20 in northwest El Paso, and its transmitter is located atop the Franklin Mountains on the El Paso city limits.


The station first signed on the air in November 1984 as KASK-TV; it originally operated as an English-language independent station. Five years later in 1989, the station changed its call letters to KZIA. Channel 48 became a charter affiliate of the United Paramount Network (UPN) upon the network's launch on January 16, 1995. In 1997, the station's calls were changed to KMAZ.

In 2001, the station's call letters were changed to KTYO. In 2004, the station was purchased by the Arlington, Virginia-based ZGS Group for $11.8 million;[2] ZGS subsequently converted the station into a Spanish-language outlet as the market's Telemundo affiliate and changed its call letters to KTDO. As a result of the switch, UPN (which ceased operations in September 2006 and merged its programming with competing network The WB as part of a joint venture between CBS Corporation and Time Warner to form The CW) did not have a full-time affiliate in the El Paso market for the remainder of the network's run, with its programming being relegated to a secondary affiliation on KKWB (channel 65, now KTFN) until it switched to TeleFutura in January 2002.

On December 4, 2017, NBCUniversal's Telemundo Station Group announced its purchase of ZGS' television stations, including KTDO.[3] The sale was completed on February 1, 2018.[4]

Digital television[edit]

Digital channels[edit]

The station's digital signal is multiplexed:

Channel Video Aspect PSIP Short Name Programming[5]
48.1 1080i 16:9 KTDO HD Main KTDO programming / Telemundo
48.3 480i 4:3 Cozi Cozi TV
48.4 T-Xitos TeleXitos

Analog-to-digital conversion[edit]

KTDO shut down its analog signal, over UHF channel 48, on June 12, 2009, the official date in which full-power television stations in the United States transitioned from analog to digital broadcasts under federal mandate. The station's digital signal remained on its pre-transition UHF channel 47.[6] Through the use of PSIP, digital television receivers display the station's virtual channel as its former UHF analog channel 48.

Former translator[edit]

KTDO's main channel was also seen in analog in El Paso proper via low-power translator KTDO-LP on channel 48, mainly to allow viewers in El Paso and on the Mexican side of the market to continue to watch the station over-the-air. With the sale to NBCUniversal and Mexico's digital transition having been completed, the license for KTDO-LP was returned to the Federal Communications Commission (FCC) on November 30, 2018, and was formally canceled on December 21.

News operation[edit]

KTDO presently broadcasts 12 hours of locally produced newscasts each week (with two hours each weekday and one hour each on Saturdays and Sundays).

On November 16, 2010, KTDO launched a news department, with half-hour Spanish-language newscasts airing at 5:00 and 10:00 p.m., under the title Telenoticias El Paso; with the launch, it became the first Spanish-language television station in the El Paso market to broadcast its local newscasts in high definition.

On June 11, 2018, the station launched newscasts at 4 and 4:30 p.m., adding to the already established 5 p.m. newscast. With this expansion, KTDO has more hours of local news than any other Spanish-language station in El Paso.[7]
