[7] Stag cinema is a form of hardcore film and is characterized as silent, usually filling a single reel or less, and was illegally made and exhibited because of censorship laws in America.

Today, many of these films have been archived by the Kinsey Institute, but most are in a state of decay and have no copyright, real credits, or acknowledged authorship.

American stag cinema in general received scholarly attention first in the mid-seventies by heterosexual males, e.g. Di Lauro and Gerald Rabkin's Dirty Movies (1976) and more recently by feminist and queer cultural historians, e.g. Linda M. Williams' Hard Core: Power Pleasure, and the "Frenzy of the Visible" (1989) and Thomas Waugh's Homosociality in the Classical American Stag Film: Off-Screen, On-screen (2001).

Restrictions, as applicable, apply to the screening, or rental, sale, or giving of a movie, in the form of a DVD, video, computer file, etc.

[10] The Independent reported in 2006 that Nielsen NetRatings found that more than nine million British male adults used Internet porn services.

[12] A 2005 study by Eric Schlosser estimated that revenues from hardcore porn matched Hollywood's domestic box office takings.

Hardcore porn videos, Internet sites, live sex acts and cable TV programming generated US$10 billion, roughly equal to U.S. domestic box office receipts.

[14] A study conducted in Denmark in 2003 and later published in Archives of Sexual Behavior found that Danish men and women generally believe that hardcore pornography has a positive influence on their lives.
