Its first production under the name, was believed to have been in 2001 with the involvement of Adam Yahiye Gadahn.
As-Sahab "produces documentary-quality films, iPod files and cellphone video." In 2007, it released 97 original videos, a sixfold increase from 2005.
More recently, the release of the "5 years after tribute", The Manhattan Raid demonstrated a standard comparing favorably with the production quality obtained by major television networks some 10 years ago. Video and audio are (depending on the source material, much of which is decades old) usually crisp, and subtitles are by and large free of grammatical and spelling errors and sometimes explain Islam-specific concepts. It is unknown whether this indicates a general increase in capability or a tapping of additional resources to produce what seems to be a kind of "special release" video.
An August 2007 study by an independent researcher has revealed that As-Sahab may be using a technology similar to greenscreen (Chroma key) to accomplish back-drop effects.
U.S. and British intelligence officials believe it to be run by former Orange County California resident Adam Gadahn, who left America to join al Qaeda in Pakistan, as first reported by ABC News last year. Although, since his alleged death in February 2008 it has been reported that the media production of these messages has gone down hill.
In 2005 a CBC programme based on a documenaty originally produced in Japan by NHK Television and was updated by the Discovery Times Channel, was released called Media Jihad - As-Sahab Foundation which traces the origins of As-Sahab.
