In 1998, TV Azteca announced an investment of US$25 million in XHTVM-TV, which was owned by Javier Moreno Valle through the concession company Televisora del Valle de México S.A. Under the deal, Azteca restructured TVM and took control of ad sales and most programming duties while Moreno Valle's CNI news service retained some prime time space. However, in 2000, Moreno Valle broke the contract with Azteca, alleging Azteca of filling up time allotted to CNI and not fulfilling the obligations in the contract. In late 2002, Azteca used private security guards to retake control of the XHTVM facilities on Cerro del Chiquihuite in Mexico City. However, the Mexican government stepped into the dispute and forced Azteca to relinquish control of XHTVM. In 2005, an employee strike that crippled CNI, Moreno Valle's mounting legal troubles, and a deal with the 5% owner of the concession company allowed Azteca to buy the remainder of the station and retake control of XHTVM, under the name Proyecto 40, in 2006.
The Federal Radio and Television Law (known as the Ley Televisa) was a bill concerning the licensing and regulation of the electromagnetic spectrum. The LFRT was favorable to both TV Azteca and Televisa (who together control 95 percent of all television frequencies) because it allowed them to renew their licenses without paying for them. According to The Economist, the Ley Federal de Radio y Televisión "raced through Congress confirming the country's longstanding television duopoly" and constituted a "giveaway of radio spectrum and a provision that allows broadcasting licenses to be renewed more or less automatically".
In February 2012, TV Azteca networks (Azteca 7, Azteca 13, and Proyecto 40) were dropped by Mexican cable-TV carriers representing more than 4 million subscribers in a carriage dispute over terms. Cable operators claimed that Azteca wanted to charge a fee by packaging its over-the-air stations with cable networks, such as news and soap opera channels, which potentially represented a higher cost to subscribers. After a nine-month absence, TV Azteca returned gradually to cable operators.
