XHTDMX was awarded in the IFT-6 television station auction of 2017, held by the
Federal Telecommunications Institute (IFT). Multimedios paid
Mex$425,929,000 for the concession. The station began testing on 12 April 2018, making it the first of the six Multimedios stations won in the auction to broadcast, and activated its second and third subchannels on 4 July. Multimedios programming officially launched programming on the main signal the night of 14 August 2018 with the launch of the second season of the network's inter-network dance competition program,
Bailadísimo, and began to have the full network programming schedule on-air as of 27 August. Multimedios is building studio facilities in Mexico City in the former home of the
Novedades newspaper to begin local program production in the capital (including a local branch of Multimedios'
Telediario news division); the network had previously used a small bureau to cover national news events in the capital. The American cable/satellite version of Multimedios carries the noon-1 p.m. and 7 p.m.-8 p.m. segments of XHTDMX's
Telediario broadcasts, along with
Futbol al Dia and
Multimedios Deportes. The network's Thursday night interview series
SNSerio also has begun to originate most weeks from XHTDMX's studios to take advantage of a larger possible guest pool. In August 2023, the IFT authorized XHTDMX-TDT to move to channel 27, which had been left vacant by the shutdown of
XHTRES-TDT the year before. == Subchannels ==
