Türkiye’s longest-running show is the police drama Arka Sokaklar, which started in 2006. It is about to finish its 20th season. So far, there has never been another Turkish weekly TV series that lasted this long.
Before Arka Sokaklar, the longest-running weekly show was Bizimkiler, a family comedy series. It told the stories and adventures of a group of people living in the same apartment building. It started on the state television channel in 1989, later moved to private TV channels, and was canceled in 2002.
Also, in our country, even daily TV shows usually last a maximum of 8–9 seasons before ending.
