Here's a question: was there a concept of privacy 100 years ago? Or 500? Whenever someone had a baby, or bought a cow, or had an affair on their spouse, didn't everyone in town know about it? Did they ask people's permission when the first telephone book was published?
Or was the first response, "hey, that's an invasion of my privacy!" I doubt anyone said that before the 1950's.
I think privacy is an invention of the late 20th century. I am truly curious if any real notion of "invasion of privacy" existed for most of man's history.
