Bonn-based Deutsche Telekom sells mobile, internet and TV services in Germany and many European countries. Most of its money now comes from the US, though, where it owns a majority of T-Mobile US, one of the three big wireless carriers. It also runs T-Systems, an IT services provider for businesses.
