A newsreel is a form of short documentary film, containing news stories and items of topical interest, that was prevalent between the 1910s and the mid 1970s. Typically presented in a cinema, newsreels were a source of current affairs, information, and entertainment for millions of moviegoers. Newsreels were typically exhibited preceding a feature film, but there were also dedicated newsreel theaters in many major cities in the 1930s and ’40s, and some large city cinemas also included a smaller theaterette where newsreels were screened continuously throughout the day.

A documentary film or documentary is a non-fictional motion picture intended to "document reality, primarily for instruction, education or maintaining a historical record". Bill Nichols has characterized the documentary in terms of "a filmmaking practice, a cinematic tradition, and mode of audience reception [that remains] a practice without clear boundaries".
