Magyar Telekom Nyrt. (officially Magyar Telekom Távközlési Nyilvánosan Működő Részvénytársaság, Magyar Telekom Telecommunications Public Limited Company[2] lit. 'Hungarian Telecom Telecommunications Public Limited Company') is the leading Hungarian telecommunications service provider company. It is a subsidiary of Deutsche Telekom.[3]
Until 6 May 2005, it was known as Matáv (Magyar Távközlési Rt. – Hungarian Telecommunications PLC). The company was formed under the name of Magyar Távközlési Vállalat (Hungarian Telecommunications Enterprise) in December 1989, when Magyar Posta (Hungarian Post) was split into three separate enterprises. On 31 December 1991, the company was re-structured as a public limited company as Magyar Távközlési Rt., and the company remained in 100% state ownership until the end of 1993. On 1 July 1993, the Telecommunications Act came into effect, making it possible to privatize the company. A consortium was formed between Deutsche Telekom and Ameritech, which was named MagyarCom, and bought into the company a share of 30.1% for a price of US$875 million.
History
Early years
On 31 December 1989, after becoming one of the three sections of the Hungarian Post service area, the Hungarian Telecommunications Company (Matáv) was founded on 31 December 1991 as telecommunications operator Magyar Telecom Rt. The company was wholly owned by the state until the end of 1993, when the Telecommunications Act, classified as a service concession to the public telephone, mobile telephone, paging and public service, came into effect 1 July 1993. A contract ended on 22 December, and Matáv became the owner of 30.1% of Deutsche Telekom and Ameritech International telecommunications companies, MagyarCom Consortium.[4] During the privatization process MagyarCom acquired a majority stake under the contract signed on 22 December 1995. The effect of the two companies forming a consortium of $852 million to 67.3% was Central and Eastern Europe's largest privatization, and also the largest foreign investment in Hungary.[5]
Deutsche Telekom's majority
On 14 November 1997, Matáv share trading began in Budapest and New York City, placing 26.31% of the shares on the market, which was the largest share subscription ever held in Hungary, making Matáv the first Central European company to be listed on the New York Stock Exchange. In the summer of 1999, ÁPV Rt. (Hungary's State Privatization Property Agency) sold the last package of shares of Hungary's 5.75%, but still held the golden share.[6]
On 3 July 2000, Deutsche Telekom acquired SBC's 50% stake in MagyarCom in compliance of their shareholder agreement. As a result of the change in the ownership structure of MagyarCom, Deutsche Telekom's ownership in Matáv increased to 59.52%, the remaining 40.48% public shareholding, while the golden share was owned by Hungary.[6]
Internationalization
Since 2001, it was possible for Matáv to become an international telecommunications group. The consortium led by Matáv acquired a majority stake in Macedonia's national telecommunications company Makedonski Telekomunikacii (MakTel), which became a consolidated subsidiary of the group.[6] As a further step, Matáv acquired the remaining 50% stake in Emitel Rt.
The group's companies took leading positions in the mobile phone, internet and business data communications markets, with a share of over 80% in the fixed phone market.[7]
A new governance structure of the group was adopted at the end of 2001.[6]
Rebranding
In 2002, the Matáv Group obtained group-level certification in accordance with ISO 9001:2000, certified by SGS S.A.[6]
Matáv also wanted to lead telecommunications and Internet services in Hungary, as evidenced by the 100,000th ADSL subscription acquired in December 2003. In mobile telephones, number portability was a minor difficulty, but the Westel division of the group solved the problem in 2004.[6]
In March 2004, the group decided to replace the Westel name, which had existed since 1989, and joined the global T-Mobile brand on 1 May 2004. Subsequently, the Matáv Group decided to consolidate and merge, subordinating the structure of the group of companies on 1 January 2005, and then on 6 May all its services and operational organizations under central management and the group of companies. It changed its company name, and from that date, the Magyar Telekom Group operated as a group of "T" brand names.[8]
On 8 November 2005, Magyar Telekom purchased Orbitel (Bulgaria's telecommunications provider), a transaction that ended on 3 February 2006.[9]
The merge caused T-Mobile Magyarország Rt. and Magyar Telekom Rt. to stop existing,[10] and András Sugár, CEO of T-Mobile, resigned. At the same time, Magyar Telekom Távközlési Nyilvánosan Működő Részvénytársaság took over their role on 1 March 2006.[6]
2007
According to the decision of Magyar Telekom’s Board of Directors as approved by the Company’s General Meeting, T-Online Hungary’s Internet access area and the regional fixed line subsidiary Emitel were integrated within Magyar Telekom as of October 1, 2007. T-Online Hungary’s web and content services business area continued to operate under the name Origo Media and Communications as a Magyar Telekom Group subsidiary.[11]
On September 25, 2007 Magyar Telekom’s Board of Directors took a decision to change the management and organization structure of the Company, in order to raise the standard of services, improve cost efficiency and exploit new, innovative service and business opportunities. The decision to change the organization model shifted the focus from technology to the demands of customer segments. Consequently, the new management structure of Magyar Telekom determines the operating model of the Group on the basis of customer segments. The new management structure, developed in order to reach the strategic objectives and based on customer segments, was implemented on January 1, 2008.[12]
2008

The number of T-Systems subsidiaries was reduced from six to two, while retaining the flexibility and customer focus.[12]
As part of Magyar Telekom’s integration processes, iWiW and Adnetwork Online Marketing merged into Origo 30 June 2008.[13]
Following the Board of Directors decision in June 2008, Magyar Telekom introduced the T-Home brand in September, which replaced the T-Com, T-Online and T-Kábel brands and has become the single brand representing fixed line communications and entertainment services at home. The corporate “T” brand has been renewed simultaneously, and it functions as an umbrella brand for the brands offered by T-Home, T-Mobile and the T-Systems. Magyar Telekom’s new slogan “Life is for sharing” was also introduced and is used both by T-Home and T-Mobile. The rebranding has created a simpler brand structure, easier to identify for customers. Along with the introduction of T-Home brand, we also repositioned Magyar Telekom as Hungary’s only “double triple-play” provider, which, through T-Home and T-Mobile, offers Internet, television and telephone services on the fixed line and mobile networks alike, at home and on the move.[14]
2009
According to the decision of Magyar Telekom’s Board of Directors as approved by the Company’s extraordinary General Meeting on June 29, 2009, the merger of cable TV subsidiaries T-Kabel Hungary and Del-Vonal into Magyar Telekom was completed 30 September 2009.[15]
