  Prosser noted that the intrusion in the first privacy right had expanded beyond physical intrusion, and pointed out that Warren and Brandeis had been concerned primarily with the second privacy right. Nevertheless, Prosser felt that both real abuses and public demand had led to general acceptance of these four types of privacy invasions. On his view, answers to three main questions were at the time as yet unclear: (i) whether appearance in public implied forfeiture of privacy, (ii) whether facts part of a “public record” could still be private, and (iii) whether a significant lapse of time affected the privacy of revelations. Note that Warren and Brandeis were writing their normative views about what they felt should be protected under the rubric of privacy, whereas Prosser was describing what courts had in fact protected in the 70 years following publication of the Warren and Brandeis paper. Thus it is not surprising that their descriptions of privacy differ. Because the Supreme Court has been explicit in ruling that privacy is a central reason for Fourth Amendment protection, privacy as control over information about oneself has come to be viewed by many as also including protection against unwarranted searches, eavesdropping, surveillance, and appropriation and misuses of one’s communications.  Thomas Nagel (2002) gives a more contemporary discussion of privacy, concealment, publicity and exposure.
