KGLA-DT is a digital-only television station that began broadcasting on June 5, 2007 under the callsign WHMM-DT. The station is also carried on selected cable systems in the New Orleans area.
KGLA's city of license, Hammond, and its transmitter in New Orleans, are both east of the Mississippi River, making it one of the few stations in the country with a "K" callsign that is east of the Mississippi River. This is possible because Mayavision owns a 50 percent share of KGLA (AM), licensed to Gretna. The "KGLA" callsign was then grandfathered to the television station.
With an ERP of 1 megawatt, the maximum currently allowed by the FCC for DTV, KGLA-DT is the only local full-power Spanish-language television station in the area. Other local Spanish-language television stations include competitors such as Azteca America affiliate WTNO-LP, and PBSsubchannelWLAE-DT3, a V-me affiliate.
On August 27, 2007, WHMM-DT changed its call letters to KGLA-TV (after its radio half-sister). On December 21 of that year, the -TV suffix was replaced with the -DT suffix in the station's callsign.
The station launched its own website in late 2007.
The station may be seen on channel 16 on Cox Cable, channel 21 on Charter, channel 11 on Comcast, and channel 42 on AT&T U-Verse, DirecTV and Dish Network.
