Most watched TV series in Turkey

Determining the all-time highest-rated TV series in Turkey can be challenging due to changing viewing habits and the evolution of rating measurement techniques over time. However, I can list some significant Turkish TV series that have received high ratings and widespread viewership over the years:

1. Muhteşem Yüzyıl (Magnificent Century): This historical drama, focusing on the life of Ottoman Emperor Suleiman the Magnificent and the intrigues of his palace, gained immense popularity in Turkey and many foreign countries.
2. Ezel: This revenge-themed series, with its compelling story and strong characters, reached a wide audience and achieved high ratings.
3. Suskunlar (Game of Silence): A significant series in Turkish TV history, it tells the story of four friends trying to cope with the traumatic events they experienced in an orphanage during their childhood.
4. Kurtlar Vadisi (Valley of the Wolves): One of Turkey's longest-running series, it deals with the mafia, internal state conflicts, and political issues, gaining a large fan base.
5. Leyla ile Mecnun (Leyla and Mecnun): Blending absurd comedy and drama, this series gained a cult status for its story and characters, followed by a broad audience.

These series are among the most-watched and highest-rated productions in the history of Turkish television. However, it can be difficult to definitively determine the all-time highest-rated series due to the variability of ratings over time.
