Step-by-step explanation:
D.W. Griffith made history in the cinematic world by producing and directing the first major full-length film, known as Birth of a Nation, which was released in 1915. Through this film, Griffith introduced many new filmmaking techniques such as advanced camera work and narrative storytelling in a feature film format.
