Al Jazeera English's Listening Post introduces the factions behind different media outlets in Iran, from President Ahmadinejad to the Supreme Leader to the Revolutionary Guards. Context includes last month's imprisonment of Ahmadinejad media advisor and editor of Iran newspaper Ali Akbar Javanfekr and the political tensions over sanctions and the country's economic problems.
The programme also looks at Iranian channels broadcasting from outside the country, including the new London-based opposition Raha TV.
