A media advisory is a notice distributed by an individual or organization, generally via fax, to members of the media. It usually outlines the schedule or details of a time-sensitive event you or your group are involved in or hosting. The information included in a media advisory includes the event's 'who, what, when, where and why' and is usually not more than a page long.
