Privacy law developed in the late 19th/early 20th century in response to the growing media. Four forms of privacy invasion were identified: appropriation, disclosure of private facts, false light, and intrusion. Appropriation involves the unauthorized use of a person's identity for commercial purposes, violating their right of publicity. Disclosure of private facts involves publicizing private information that is highly offensive. False light involves misrepresenting someone in a highly offensive manner. Intrusion involves invading someone's physical privacy or private affairs. However, privacy torts must be balanced with First Amendment rights and considerations of newsworthiness. Consent is also important to avoid privacy issues.
