If you want a good tech example of how courts evolve the definition of phrases as society evolves, you need look no farther than the word "eavesdropping." We use that word all the time today, but why do we call it that? When towns started to give way to cities, the spacing between houses began to shrink to the point where rain could cause water to spill off the roof of one house onto their neighbors property, a process that was called eaves dropping because the water dropped off the eaves of the roofs. Who owned that water and who was liable for the damages it might cause became a thing courts needed to address. That English common law decision, that courts could adjudicate the ownership of and damages caused by things that unintentionally pierced property boundaries "because water" is today the legal basis for a broad class of infosec law that we think of as eavesdropping law.

EDIT: HN won't let me respond to the question below on sources. This comes from a physical copy of the 1911 Encyclopedia Britanica, which has Eavesdropping as an entry and only discusses the water dropping off roofs meaning, strongly suggesting that our modern use of the term had not become common by that point.
