Iran's newspapers are currently going through some of their hardest times, and the future is uncertain following the election of the conservative Mahmoud Ahmadinejad as the country's president in June 2005.
There is a large number of daily and weekly newspapers and the press reflects a range of political viewpoints, albeit within the limits allowed by the law and constitution. All publications have to be licensed, and there have been periodic crackdowns on reformist newspapers and journalists seen as going beyond acceptable limits.
When President Ahmadinejad came to power there were fears in some quarters that this would see a renewed crackdown on pro-reform media. Although there has not been a repeat of the mass closure of newspapers that occurred in 2000, there have been reports of journalists being summoned by various official bodies and warned against publishing articles critical of the government.
The Supreme National Security Council has also intervened. In particular, it has warned the media against publishing analyses on the nuclear issue and negotiations with the US that differ from official policy.
Newspapers in Iran now face a number of major challenges. They are under pressure from their readers to be more open, while the government insists that they should not step out of line.
Readership figures are in decline and Iran's advertising market is limited. There is also a shortage of imported and domestically produced paper.
The internet is becoming a player in the Iranian media scene. Nearly seven million Iranians are now estimated to be online, and the internet is developing into a serious alternative source of news.
Sports papers enjoy the widest circulations. Some two million copies are read every morning. Their circulation often doubles after a major soccer match.
The main conservative dailies include:
One of the country's oldest daily papers, run by the office of the Supreme Leader, who appoints the managing editor. Read by a conservative, religious audience. It has consistently taken a hard line on domestic and foreign policy issues and published articles about those accused of working for the CIA or other agencies. Circulation 60-100,000.
Established in 1985 and owned by the Resalat Foundation, which has strong links to the traditional bazaar merchants - conservative but in favour of a market economy. It reflects the views of the conservative Islamic Coalition Party and the Islamic Association of Engineers. Read by a conservative, religious audience. Circulation 30,000-50,000.
Ayatollah Ali Khamene'i, Iran's supreme leader, was the first licence holder and the paper is considered still to be closely linked to him. The paper adheres to Khomeyni's ideals and has consistently taken a radical position on foreign policy issues and a conservative position on domestic and religious issues. Circulation: n/a.
