We don't need to reverse-engineer the Turkish model. We had our own model that worked a lot better than the Turkish model during the Shah's time.
You have to understand that Iran enjoyed incredible amount of soft power during the Shah's time. Millions of people in the region continue to listen to Persian music from the time of the Shah, including people in Turkic countries, Arab countries and Southern Asia. Artists like Googoosh, Haydeh, Dariush, etc. all have millions of fans in the region outside of Iran.
The Ayatollahs are inherently against arts and culture. It's not going to change as long as these idiots are in power. The only exception was during the time of Ahmadinejad when he heavily invested in international channels like PressTV, iFilm and even a Spanish channel for Hispanic people in Latin America and it had limited success but as soon as he left, the system decided to ruin all his legacy. Khatami also played a huge role in reviving arts and culture after the 1979 revolution.
