Deutsche Telekom AG (About this sound listen ) (short form in writing only: DT ) is a German telecommunications company headquartered in Bonn and by revenue the largest telecommunications provider in Europe. Deutsche Telekom was formed in 1996, as the former state-owned monopoly Deutsche Bundespost was privatised. The company operates several subsidiaries worldwide, including the mobile communications brand T-Mobile.

As of April 2018, the German government holds a 14.5% stake in company stock directly, and another 17.4% through the government bank KfW.[4] The company is a component of the Euro Stoxx 50 stock market index.[5]


The Deutsche Bundespost was the federal German government postal administration created in 1947 as a successor to the Reichspost. It was also the major telephone company in West Germany.

On 1 July 1989, as part of a post office reform, Deutsche Bundespost was split into three entities, one being Deutsche Telekom. On 1 January 1995, as part of another reform, Deutsche Bundespost Telekom became Deutsche Telekom AG, and was privatized in 1996. As such, it shares a common heritage with the other privatized Deutsche Bundespost companies, Deutsche Post (DHL) and Deutsche Postbank.[6][7]

Deutsche Telekom was the monopoly Internet service provider (ISP) for the German Internet until its privatization in 1995, and the dominant ISP thereafter.[8] Until the early 21st century, Deutsche Telekom controlled almost all Internet access by individuals and small businesses in Germany, as they were one of the first German telecom units.[8]

On 6 December 2001, Deutsche Telekom became the first official partner of the 2006 FIFA World Cup.[9]

On 1 January 2005, Deutsche Telekom implemented a new company structure. The two organizational business units of T-Com and T-Online were merged into the Broadband/Fixed Network (BBFN) strategic business unit (T-Online merged with parent Deutsche Telekom in 2006). It provides around 40 million narrowband lines, over 9 million broadband lines and has 14 million registered Internet customers.

In 2008, the structure was changed again. T-Online was separated from Deutsche Telekom, and merged with T-Com to form the new unit T-Home. In September 2010, Orange parent France Télécom and T-Mobile parent Deutsche Telekom merged their operations in the United Kingdom to create the largest mobile network in Britain, EE.[10]

In April 2010, T-Mobile was merged with T-Home to form Telekom Deutschland GmbH. This unit now handles all products and services aimed at private customers. In October 2012, Deutsche Telekom and Orange created a 50-50% joint venture named BuyIn for regrouping their procurement operations and benefiting from economies of scale.[11]

In April 2013, T-Mobile US and MetroPCS merged their operations in the United States.[12] In February 2014, Deutsche Telekom acquired the remaining parts of its T-Mobile Czech Republic division for around €800 million. The size of the remaining stake was numbered at 40 percent.[13]

In December 2014, it was announced that Deutsche Telekom were in talks with BT Group on the acquisition of EE, and part of the deal was to provide Deutsche Telekom a 12% stake and a seat on the board in the BT Group upon completion.[14][15] BT Group announced agreement in February 2015 to acquire EE for £12.5 billion[16] and received regulatory approval from the Competition and Markets Authority on 15 January 2016.[17] The transaction was completed on 29 January 2016.[18]
