Step 1: Concept
The Supreme Court of the United States established a three-pronged test for determining whether content is obscene.
Step 2: Meaning
Obscene content refers to material that lacks serious literary, artistic, political, or scientific value and appeals to prurient interests. The Miller v California case provided a framework for evaluating such content.
Step 3: Analysis
In 1973, the Supreme Court of the United States decided on the case of Miller v California. This landmark decision introduced the "Miller test," which consists of three prongs:
1. Whether the average person, applying contemporary community standards, would find that the work, taken as a whole, appeals to the prurient interest.
2. Whether the work depicts or describes, in a patently offensive way, sexual conduct specifically defined by applicable state law.
3. Whether the work, taken as a whole, lacks serious literary, artistic, political, or scientific value.
The other options provided do not pertain to this specific case:
New York vs S. Griffin (1976) is unrelated to obscenity laws.
Week vs Boston (1974) does not address the issue of defining obscene content.
Washington Post vs TV-PG (1978) concerns media ratings, not obscenity standards.
Step 4: Conclusion
The court case that defined obscene content according to a three-pronged test is Miller v California in 1973.
