Pornography
Pornography can be made in different media.  Some ways include photos, drawings, paintings, animations, and movies. Live shows (like sex shows or striptease) are usually not considered pornography. Pornography is made to entertain adults. Many people are involved in the industry of making, selling, or showing pornography.  People shown in pornographic movies are called pornographic actors (or actresses), and when they attain the popularity to appear in many films, they are called "porn stars."
