AFI 100 Years... series
The AFI's 100 Years… series was a series of annual lists from 1998 to 2008 by the American Film Institute—typically accompanied by CBS television specials—celebrating the century of American cinema. As a centennial celebration of cinematic milestones, the series intended to inspire discussion and public interest in classical Hollywood cinema. As such, each list only included feature-length American films that were typically released before 2005. AFI defined "American film" as an "English language motion picture with significant creative and/or financial production elements from the United States;" and "feature-length film" as a  motion picture of narrative format that is typically over 60 minutes in length. To determine the composition of these lists, the names of a few hundred nominated films were listed on ballots that AFI would distribute to a jury of over 1,000 leaders in the creative industry, including film artists (directors, screenwriters, actors, editors, cinematographers), critics, and historians.
