Telmex is a Mexican telecommunications company headquartered in Mexico City that provides telecommunications products and services in Mexico, Argentina, Colombia, Brazil (Embratel), Ecuador and other countries in Latin America. Telmex is still the dominant fixed-line phone carrier in Mexico.[clarification needed] In addition to traditional fixed-line telephone service, Telmex also offers Internet access, data, hosted services and IPTV. Telmex owns 90 percent of the telephone lines in Mexico City. Telmex is a wholly owned subsidiary of America Movil.
Telmex was founded in 1947 when a group of Mexican investors bought Swedish Ericsson's Mexican branch. In 1950, the same investors bought the Mexican branch of the ITT Corporation, thus becoming the only telephone provider in the country. In 1972, the Mexican government bought the company, turning it into a government monopoly.
In 1990, Telmex was bought by a group of investors formed principally by Carlos Slim Helú, France Télécom, and Southwestern Bell Corporation, whose tender was the largest. However, controversially, the payment itself took place over the course of the next several years, using revenues from the phone service.
After privatization, Telmex began investing in new modern infrastructure, creating a nationwide fiber optic network, thus offering service to most of the country.
In 1991, the Mexican government sold its remaining stock in Telmex.
In the 1990s, mobile telephones were becoming popular among the general population. The early market leader was Iusacell, and Telmex had no presence in the market. This prompted Telmex to form a subsidiary to provide mobile communications. The subsidiary was Radio Móvil Dipsa, and it offered service under the brand Telcel. Telcel started out in a distant second place in its mobile market, but in 1995 everything changed, when the Mexican currency crisis hit many Mexicans hard. Iusacell decided to stay with wealthier customers, offering expensive plans, whereas Telcel began to offer the first prepaid mobile phone plans. Although, in effect, just as expensive as the contracts offered by Iusacell, the success of its prepaid plans ultimately provided Telcel the growth needed to become the leader in the mobile market within two years.
In 2000, Telmex spun off their mobile unit, creating América Móvil, which controls Radio Móvil Dipsa and was free to develop as its own business as an independent entity. It started with 80% of the mobile market. Some people[who?] incorrectly continue to believe that América Móvil is part of Telmex. Instead, both are sister companies under parent Carso Global Telecom, and Carso Global Telecom is itself a sister conglomerate of Grupo Carso. Carso Global Telecom was taken over by America Movil in mid-2010.
In the mid-1990s, Telmex began providing 
In 2001, Telmex sold the U.S. branch of SBC Prodigy. However, Telmex continues to own and operate Prodigy in Mexico.
In 2004, Telmex claimed that the number of users of Prodigy Internet grew by 190%.
In the mid-1990s, AT&T Corporation and WorldCom (MCI), among others, began operating in Mexico, representing for the first time serious competition to Telmex. However, due to Telmex's incumbent monopoly position and well-developed infrastructure and coverage, none of them were believed to pose much threat to Telmex.
After spinning off América Móvil, Telmex started an expansion plan, which started with the purchase of Guatemala's Telgua. Later, Telmex bought former state-owned phone companies in Central America, and began operations in the USA with Telmex USA.
In 2004, Telmex went into a shopping spree for undervalued operators in South America, including the purchase of AT&T's Latin American operations, giving it presence in Colombia, Peru, Chile, Argentina, Brazil, and Uruguay, and increased reach in the United States. In the same year, Telmex bought from MCI Brazil's largest and most important long distance operator, Embratel, acquired Chile's Chilesat, took control of Argentina's Techtel (operating in Argentina and Uruguay), of which it already owned 60%, by purchasing the remaining 40% from the Techint group, and purchased Argentina's Metrored. In the USA, Telmex bought 13.4% of bankrupt MCI.
At the same time, sister company America Movil pursued a similar strategy by acquiring cellular operators CTI Movil in Argentina and Uruguay, Claro in Brazil and Peru, Porta in Ecuador and Comcel in Colombia.
In 2005, Telmex sold its holdings in MCI to Verizon.
As of January 2006, Telmex continued buying assets in Latin America and in the USA.
In March 2006, there were rumors that Telmex was buying Verizon operations in the Caribbean. The reports said that the operation can include the wireless operation on each market. The total amount of this sale was estimated at nearly US$300 million.
In November 2006, an American embassy cable released via Wikileaks listed Telmex as among "Mexico's monopolists", with a 95% share of landlines. Its competitor Telcel was listed with a market share of 80% of cellular service.
In December 2006, Telmex announced agreement to acquire TV Cable and Cable Pacifico in Colombia. TV Cable offers cable television, Internet and Voice over IP services and has been in operation for 20 years. As of 2013[update], the company serves 164,000 homes in Bogotá and Cali. Cable Pacifico serves nine states and its main operation is in Medellín. As of 2013[update], Cable Pacifico has approximately 100,000 subscribers.
In January 2007, America Movil bought the Verizon operations in Puerto Rico, and days later Telmex and America Movil announced that their equally owned joint venture had agreed with Verizon Communications Inc. (“Verizon”) to terminate the joint venture's agreement to acquire Verizon’s indirect equity interests in Compañía Anónima Nacional Teléfonos de Venezuela (CANTV); subsequently, all of Verizon's holdings in CANTV were acquired in May 2007 by the Venezuelan government, reaching 86.2% of its total shares.
In January 2007, Telmex launched Prodigy Media, the first step to offer triple play services to the Mexican market. Days later, Telmex started the first Wi-Max network in Chile, offering local, long distance and Internet services to 98% of the Chilean population.[dubious ]
In March 2007, Telmex bought Ecutel, a small telecommunications company in Ecuador that offers services to the corporate market.
In April 2007, Telmex announced agreement to acquire CABLECENTRO and SATELCARIBE in Colombia. CABLECENTRO offers cable TV and Internet access services and has been in operation for 7 years.[when?] Currently, the company operates in more than 50 cities in Colombia including Bogota, Cucuta, Bucaramanga, Ibague and Neiva, among others. SATELCARIBE offers cable TV and Internet access services and has been in operation for 7 years. Currently, the company operates in more than 15 cities in Colombia including Cartagena, Santa Marta, Valledupar, Sincelejo and Monteria.
In December 2007, Telmex transferred its Latin American and yellow pages directory businesses to a new, separate entity, Telmex Internacional.
In January 2010, America Movil, the largest mobile phone company in Latin America, made an offer to buy Telmex and Telmex International in order to better compete against Spain's Telefonica. The acquisition was approved by the CFC (Comisión Federal de Competencia) Antitrust Office in Mexico on February 11, 2010.
America Movil was once the mobile arm of Telmex, but in 2001 America Movil was split off and grew larger than the former parent company.
