Here is what I found from a US House joint hearing on February 16, 2005:
"At the time of al-Manar's founding in 1991, the station reportedly received seed money from Iran and had a running budget of $1 million. By 2002 its annual budget had grown to approximately $15 million. Middle East analysts and journalists maintain that most of this funding comes from Iran. Avi Jorisch, author of Beacon of Hatred: Inside Hezbollah's al-Manar Television, writes that "Iran provides an estimated $100-200 million per year to Hezbollah, which in turn transfers money to al-Manar, making Iranian funding of the station indirect." This was confirmed by former al-Manar program director Sheikh Nasir al-Akhdar who asserted that al-Manar receives a large portion of its budget through subsidies offered by Hezbollah."
