Pornography is sexual material — movies, books, songs, etc. — that are 100% about sex. They have no other value.
Pornography features people having sex, and it is intended to get viewers sexually excited. If there is also a complicated plot, interesting characters, amazing music, or fantastic direction, then we're probably not talking about pornography anymore. Pornography is only about the sex. Also called porn or a porno, pornography is illegal for young people to look at or participate in. Pornography is for adults.
