- On May 31, 2006, Deutsche Telekom appealed to the approximately 400 German cities with populations of between 25,000 and 100,000 residents to apply for T-City.
- Interested municipalities had the opportunity to get involved and come up with their own visions and project ideas until the end of October.
- Researchers in the Department of Geography at Bonn University evaluated the applications.
- On December 1, 2006, an independent jury made up of representatives from the media, business and politics chose 10 finalists out of the 52 participating cities: Arnsberg, Coburg, Frankfurt (Oder), Friedrichshafen, Görlitz, Kaiserslautern, Kamp-Lintfort, Neuruppin, Osterholz-Scharmbeck and Schwäbisch-Hall.
- Those cities had until the end of January to submit their revised applications.
- After assessing these and visiting the 10 final-round cities, the jury made its decision in mid-February: Friedrichshafen would become T-City.
- On February 21 in Bonn, Deutsche Telekom CEO René Obermann presented the mayor of Friedrichshafen, Josef Büchelmeier, with the winner’s certificate.
- With “T-City Friedrichshafen. Living the future” as a motto, the city became a future lab and a partner of Deutsche Telekom for the next five years.
