There are some productions that have been on the air in Germany for more than half a century that eventually cease to be a television program, turn into a social habit, even a collective memory. Tatort is exactly such a thing. This German crime series, which has been running continuously since 1970, not only tells a crime story today with 57 seasons and more than 1300 episodes, but also reveals the last fifty years of Germany, its changing social dynamics and the way people face their dark nature. In each episode, you encounter different detectives in a different city. This structure gives the series both a local and a national identity. This geographical diversity, which stretches from the ports of Hamburg to the streets of Munich, from the gray back neighborhoods of Cologne to the towns of East Germany that are in the throes of transformation, turns Tatort into a portrait of a country. The on-screen viewing of millions of German viewers on Sunday evenings has become an ongoing ritual for decades; in this aspect, the series is also worth examining from a sociological point of view as a cultural phenomenon. What sets Tatort apart from a typical crime drama is its use of the crime phenomenon as a social lens. Detectives pursuing a murder uncover not only the perpetrators, but also racism, poverty, institutional corruption, domestic violence and the invisible wounds of modern life. The series boldly touches on many sensitive issues, from the process of German unification to the devastating effects of globalization, from environmental crimes to the deep decay of the health system. These episodes are sometimes as suspenseful as a thriller, and sometimes as thought-provoking as a text of social criticism. Watching Tatort means encountering a different side of Germany every time. The series is not flawless; the variability over decades has led to fluctuations in quality. However, even this inconsistency adds a unique human dimension to it. Unlike real life, the crime is always solved and the perpetrator is always found; but the questions it leaves behind are never fully resolved. That's why Tatort has gone far beyond a television series and evolved into a long-running, living novel that portrays German society.
