Overview
XHTVM-TDT is a commercial open television station serving the Valle de México, licensed to Televisora del Valle de México, S.A.P.I. de C.V. It broadcasts on digital channel 26 under the ATSC standard with an apparent radiated power of 513.050 kW, having ended analog UHF channel 40 transmissions on 17 December 2015. The station is currently operated by TV Azteca and is the originating station of the Proyecto 40 signal, today known as ADN Noticias (adn40). The station's history is closely tied to the career of Javier Moreno Valle, who in April 1993 received the commercial concession for UHF channel 40 in Mexico City and the metropolitan area. Test transmissions began on 5 December 1994, with official broadcasts starting on 19 June 1995 from studios at the World Trade Center in Mexico City. Moreno Valle created Corporación de Noticias e Información (CNI) to produce the channel's core programming, which focused on newscasts and investigative journalism, positioning itself as an alternative to the dominant Televisa newscasts. In its early years, much of the schedule consisted of retransmissions of Classic Arts Showcase (known as ARTS) and the extinct Spanish-language news network Telenoticias. CNI Canal 40 became known for a style perceived as "contestataria" (oppositional) and impartial, with programs such as CNI Noticias, Séptimo Día, En el Límite, Las Nueve y Sereno, El Mañanero (featuring comedian Victor Trujillo as Brozo) and the documentary series Realidades. To obtain additional resources, Moreno Valle entered a commercial agreement with TV Azteca. Under the arrangement, TV Azteca would provide programming from 12 AM to 9 PM, sell advertising in that block, and produce promos for the entire schedule; the agreement also gave TV Azteca the option to acquire TVM shares if the company decided to transfer them to a third party. On 4 December 1998, TV Azteca began broadcasting the Azteca 40 signal over XHTVM, leaving CNI to operate the channel from 9 PM to 11:59 PM. On 16 July 2000, TVM stopped transmitting the Azteca 40 signal and broadcast only CNI-produced programming. On 23 July 2000, in an interview with Ciro Gómez Leyva on CNI's Séptimo Día, Javier Moreno Valle said he did not recognize the agreements with TV Azteca, arguing that their purpose was to bankrupt TVM so it could be acquired cheaply, and that Azteca 40 confused viewers into thinking XHTVM was already TV Azteca property. TV Azteca considered the decision illegal and unilateral and began a long legal conflict, initially obtaining an injunction to enforce the agreement and its purchase option. The dispute went to the International Court of Arbitration of the International Chamber of Commerce in Paris. On 21 December 2002, an award favored TVM and CNI and blocked TV Azteca from acquiring TVM shares. TV Azteca rejected the award and on 27 December 2002 took over the XHTVM transmission plant on Cerro del Chiquihuite, displacing CNI's signal with Azteca 40. The incident, known as El Chiquihuitazo, was reportedly carried out with the help of an armed commando, which TV Azteca denied. CNI Canal 40 continued via streaming and on pay-TV systems. On 24 January 2003, judge Luz María Díaz Barriga granted CNI a provisional injunction ordering an end to the seizure of the transmission plant, and CNI Canal 40's signal was restored on 27 January. The end of El Chiquihuitazo did not resolve TVM and CNI's problems. Lack of resources, worsened by the break with Azteca and problems with other creditors, led unionized workers of Televisora del Valle de México to consider strikes on several occasions. The conflict with TV Azteca also produced complaints by that company accusing Javier Moreno Valle of fraud over loans. Today the station is operated by TV Azteca and carries the ADN Noticias brand, whose website adn40.mx publishes Mexican and international news.
History
XHTVM-TDT traces its origins to April 1993, when the Mexican government granted a commercial concession for UHF channel 40 in Mexico City and the metropolitan area to Televisora del Valle de México, S.A. de C.V., a company owned by Javier Moreno Valle. Test transmissions began on 5 December 1994, and official broadcasts started on 19 June 1995 from studios and offices at the World Trade Center in Mexico City. Moreno Valle created Corporación de Noticias e Información (CNI) to produce the channel's base programming, aimed at newscasts and investigative programs, at a time when much of the Mexican public held a negative perception of the main networks' newscasts, especially Televisa's. In its early years, a large part of the schedule consisted of retransmissions of Classic Arts Showcase (known simply as ARTS because of its logo) and the signal of the extinct Spanish-language news network Telenoticias. CNI Canal 40 stood out for a news production style perceived as "contestataria" and impartial. Notable programs included CNI Noticias, Séptimo Día, En el Límite, Las Nueve y Sereno, El Mañanero (with comedian Victor Trujillo as his character Brozo) and the documentary series Realidades. Seeking additional resources to keep the channel afloat, Javier Moreno Valle made a commercial agreement with TV Azteca. Broadly, the agreement allowed TV Azteca to provide programming from 12 AM to 9 PM, obtain advertisers in that same time block for the sale of products or services, and produce promos for all programming. It also allowed TV Azteca to acquire shares of TVM if the company decided to transfer them to a third party, whether partially or in full. On 4 December 1998, Ricardo Salinas Pliego's television company began broadcasting the Azteca 40 signal over XHTVM, leaving CNI to operate the channel from 9 PM to 11:59 PM. On 16 July 2000, TVM stopped transmitting the Azteca 40 signal and broadcast exclusively the signal produced by CNI. On 23 July 2000, in an interview with Ciro Gómez Leyva on CNI's Séptimo Día, Javier Moreno Valle announced that he did not recognize the agreements with TV Azteca, considering that their objective was to bankrupt TVM so it could be acquired at low cost, taking advantage of the priority given to TV Azteca for that purpose under the agreement. Moreno Valle's argument was that Azteca 40 confused people into thinking XHTVM was already TV Azteca property and that, besides the fact that CNI promotion was not aired on channels 7 and 13, Azteca 40 programming had taken space from several CNI programs, especially by having its own news spaces. TV Azteca considered this decision illegal and unilateral and began a long legal conflict. Initially, TV Azteca obtained an injunction so that the agreement would be respected and it could exercise its purchase option. The legal and commercial conflict between TVM and TV Azteca was taken to the International Court of Arbitration of the International Chamber of Commerce in Paris, France. On 21 December 2002, an award was issued favoring TVM and CNI and preventing TV Azteca from acquiring TVM shares. TV Azteca rejected this award and in response, on 27 December 2002, the XHTVM transmission plant on Cerro del Chiquihuite, north of the Federal District, was seized, with the Azteca 40 broadcast completely displacing CNI's signal. This incident (said to have been carried out with the help of an armed commando, which TV Azteca has denied) is known as El Chiquihuitazo. In response to the Azteca 40 signal, the CNI Canal 40 signal, unchanged, remained via streaming on CNI's website and on pay television systems in the country. Over the course of a month, various actions were taken by those involved, such as TV Azteca's attempt to hire TVM and CNI staff, marches and public demonstrations by TVM and CNI workers, suspension of the XHTVM signal, and the SCT's securing of the transmission plant. Finally, on 24 January 2003, judge Luz María Díaz Barriga granted CNI a provisional injunction and ordered an end to the securing of the transmission plant on Cerro del Chiquihuite to restore the CNI Canal 40 signal, which happened on 27 January. The end of El Chiquihuitazo would not end the problems for TVM and CNI. The lack of resources, which worsened with the break with Azteca and problems with other creditors, led unionized workers of Televisora del Valle de México to consider going on strike on several occasions. The conflict with TV Azteca gave rise to several complaints by that company accusing Javier Moreno Valle of fraud over loans. Today the station is operated by TV Azteca and is the originating station of the Proyecto 40 signal, now ADN Noticias, whose website adn40.mx publishes breaking news and live information.
