The early years in the development of privacy rights began with English common law which protected "only the physical interference of life and property". The Castle doctrine analogizes a person's home to their castle – a site that is private and should not be accessible without permission of the owner. The development of tort remedies by the common law is "one of the most significant chapters in the history of privacy law". Those rights expanded to include a "recognition of man's spiritual nature, of his feelings and his intellect." Eventually, the scope of those rights broadened even further to include a basic "right to be let alone," and the former definition of "property" would then comprise "every form of possession – intangible, as well as tangible." By the late 19th century, interest in privacy grew as a result of the growth of print media, especially newspapers.
