The German system, called "Teletext" is still alive and kicking. See for example http://ardtext.de/ and http://zdftext.de/ of the first and second TV channel in Germany. Even in times of the Web it's often faster to get the latest sports results through teletext (if you just want the results and no clutter).
Small point: Teletext is not the "German" system, it's the generic name for the service. The UK had several Teletext services, such as Ceefax (BBC channels) and Oracle (independent channel). Similarly ARDText and ZDFtext are German Teletext services.
