Tatort ("Crime scene") is a German language police procedural television series that has been running continuously since 1970 with some 30 feature-length episodes per year, which makes it the longest-running German TV drama.
 Developed by the German television channel ARD, it is unique in its approach, in that it is jointly produced by all of the station's regional public-service broadcasters whereby every regional station contributes a number of episodes to a common pool.
 Therefore, the series is a collection of different police stories where different police teams each solve crimes in their respective city.
 Uniqueness in architecture, customs and dialects of the cities is therefore a distinctive part of the series and often the city, not the police force is the real main character of an episode.
 The concept of local stations only producing a couple of shows per year has also enabled the shows to be longer (90 minutes) and more fleshed out psychologically than other weekly TV dramas.
