Qaradawi has established a worldwide following through television appearances and by utilizing the Internet.  He was relatively quick to take advantage of the Internet, launching a site in his name in 1997.  The site includes several of his fatwas supporting terror.  In 2006, Qaradawi used his Web site to denounce a Danish newspaper's cartoon of the Prophet Muhammad and declared February 3, 2006, an "international day of rage." 

Qaradawi hosts a weekly television show called "Shariah and Life" on the Arabic-language television news network, Al Jazeera, where he also expresses his support for terror.  For example, during an April 2004 show, he credited Allah with providing Palestinians "human bombs," instead of the planes, missiles and weapons that Zionists have.  In addition, his Friday sermons at the Umar bin al-Khattab mosque, a government-sponsored mosque in Doha, have been regularly broadcast live on Qatar television.  In a 2005 sermon, while speaking about notable Hamas leaders killed by Israel, Qaradawi asserted, "Their fate was paradise. They died martyrs. They met the death that every Muslim wishes for himself, which is martyrdom in the cause of God."

Qaradawi is also influential through a wide network of affiliations. In the U.S., he is the chairman (in abstenia) of the Michigan-based Islamic American University (IAU), a subsidiary of the Muslim American Society (MAS), according to the MAS Web site.  The university aims to provide Islamic higher education, especially to converts and non-practicing Muslims, according to the IAU Web site.  Qaradawi is also listed by the IAU as a faculty member. 

Prior to being banned from the U.S. in 1999, Qaradawi reportedly spoke to several Muslim organizations around the country.  For example, Qaradawi spoke at the now-defunct Muslim Arab Youth Association (MAYA) conference in Toledo, Ohio, in 1995, where he stated, "If everyone who defends his land and dies defending his sacred symbols is considered a terrorist, then I wish to be at the forefront of the terrorists.  And I pray to Allah if that is terrorism, then O Allah make me live as a terrorist, die as a terrorist, and be raised up with the terrorists."  

Despite the ban, Qaradawi's message still reaches the American public via satellite television and the Internet, in particular IslamOnline, a Web site published in both Arabic and English.  The site contains articles and religious rulings which support violence against non-Muslims, as well as anti-Semitic, anti-Israel and anti-American content.

Qaradawi has also written over 40 books, many of which have been published in different languages and disseminated throughout the world.  In one of his books, Priorities of the Islamic Movement in the Coming Phase (1990), Qaradawi emphasizes the need for unity among Muslims in what he refers to as a fight against the Jews' ambitions in the Middle East.
