Deutsche Telekom is Germany’s largest telecommunications firm and the third largest in the world, being a global leader in innovation in the telecommunications sector. Headquartered in Bonn, Germany, Deutsche Telekom is Germany’s leading provider of fixed-line telephone service and provides a slew of phone services to over 100 million subscribers all around the world.

Humble Beginnings

In 1833, the first optical telegraph was introduced in Prussia, a German state at the time. In 1846, the first telegraph line was connected between Berlin and Potsdam. In 1877, the first postmaster of Germany’s united postal system Deutsche Bundespost, Heinrich von Stephan, conducted an experiment with two telephones built by American inventor Alexander Graham Bell.

This resulted in voice being successfully transmitted over a wire. Heinrich von Stephan realized the potential of this communication system and placed the telephone services under the control of his postal authority, the Bundespost.

Pre Second World War

In 1881, telephone networks were being constructed and installed in other German cities, such as Hamburg, Frankfurt, and Cologne. By 1898, the number of telephone subscribers leaped to 46,000, the highest in Europe at the time. Just before the outbreak of the Great War, many telephone lines were already being installed underground.

By the 1920s, millions of people were connected to each other by telephone technologies under the company called Bundespost. In 1926, for the first time, train passengers commuting between Berlin and Hamburg could call anywhere in the world!

Nazi Germany

A dark moment in history, the Nazis regularly intercepted telephone communications to identify certain groups of people. Bundespost was operating throughout the war and even after the downfall. Hundreds of thousands of buildings and stations were destroyed during the bombings and all seemed in ruin. However, the company held strong and rebuilt the network in 1949 with the help of the British and American governments.

The Bundespost was now a government entity with the Federal Republic of Germany having assumed control over posts, telephones, and telegraphs. What was once a private organization became a government institution.

Post Second World War

Bundespost rebuilt its communications network and total infrastructure. The telephone service was entirely reconstructed in 1951, but there was still a lack of private telephones at home. However, by the 1960s, Germany’s complete telecommunications network was restored. There was a high demand for telephones, and Bundepost was there to supply their customers.

After the devastating events of WWII, Germany experienced an economic boom and many businesses relied on communications to conduct their operations. In 1989, the Deutsche Bundespost was divided into three companies: Deutsche Bundespost Postdienst, Deutsche Bundespost Postbank, and Deutsche Bundespost Telekom.

Reunified Germany

German reunification lead to the integration of East Germany’s own telecommunications company, Deutsche Post, with Bundespost. Only 10% of household in East Germany had telephone connections, compared to 98% in West Germany. Far too much bureaucracy inhibited civilians in East Germany to acquire telephones in their home.

Within 6 months after reunification, Deutsche Bundespost Telekom launched the Telekom 2000 program, a 7-year investment plan aimed at bringing the telecom network of East Germany on the same platform as that in West Germany. It was also used to install a state-of-the-art infrastructure that met the demands of the 21st century and beyond.

Road to International Growth

In 1995, Deutsche Telekom announced a strategic alliance with France Telecom and Sprint called Global One. In 1999, Deutsche Telekom’s ISP T-Online was rebranded as T-Online International AG. The company was very highly profitable.

In 2001, Deutsche Telekom finalized a takeover of American phone service providers VoiceStream Wireless Corporation and Powertel, Inc. The collaboration allowed Deutsche Telekom to offer travelers between Europe and the US one phone number and one rate for voice and data services.

Also in 2001, Deutsche Telekom restructured its business organization again. Conforming to the company’s new strategy, all activities were organized in four business divisions: T-Mobile, T-Online, T-Systems, and T-Com. In the systems applications field, Deutsche Telekom took over software systems developer Systemhaus GmbH. In the sector of network access, Deutsche Telekom focused on acquiring new customers high-speed digital ISDN and broadband T-DSL services.

Despite many difficulties encountered along the way of all these advancements, Deutsche Telekom is the number one phone company in Germany and one of the biggest in the world in the telecommunications market.

Starting in Germany, the technology and reach of Deutsche Telekom extended to the rest of Europe and eventually extended to other continents. This is only possible with the large investments made in research and development as well as the firm working with partners to always find the next best technology.

In addition to help services available online and over the phone, the company knows that the best way to establish a strong presence and communication with customers is to have customer care points in cities where services are being offered. Subscribers can drop by the customer care center and talk to a member of tech support face-to-face and explain their problem, whether it be a hardware or software related issue. To provide continuous support to customers shows Telecom’s commitment and dedication to their customer base.

Key Activities

The business model of Deutsche Telekom involves establishing new international standards and to promote and facilitate the sustainable development of environment and society.

This helps keep the stakeholders of the firm interested in corporate social responsibility while the company is simultaneously able to make a mark in history in telecommunications.

“Win with Partners” is one of the four key elements of Deutsche Telekom’s strategy. This highlights the importance of cooperation for the organizations future success. The company continues to develop its own ideas but it is always open to concepts from other groups and it is increasingly emphasizing the significance of collaborations. From large corporations to small startups, anybody can become a partner on equal terms with Deutsche Telekom.

Key Resources

People are the reason why Deutsche Telekom is as successful as it is today.

With well over 200,000 employees in multiple locations around the globe, Deutsche Telekom has a varied team of sales and marketing staff in addition to excellent engineers and researchers who are always developing new technologies to advance communications.

This guarantees that the products are unique and cannot be copied by the competitors.

The technically gifted individuals make the company what it is today, but there needs to be infrastructure to make it all happen.

This is a necessary business function and keeps the business in prime position.
