"...MPR’s Midmorning and NewsCut Blog about our society’s current concern over privacy rights. One of the commentators noted that human society, from the days we first walked upright until the last century, lived with little to no privacy in day-to-day life. Sure there wasn’t the same kind of access to information like there is now, but pretty much wherever you went, people knew your name, who your family was and many other details..."
A teenage farm boy in the 1800s could meet his girlfriend behind the haystack and nobody would ever know unless they were physically seen. A factory worker required physical oversight. In general a telephone call or first class letter in 1900 was assumed to be private.
Today, that teenager's real-time GPS location can be tracked by "parental monitoring" software on his cell phone. It can eavesdrop on his face-to-face conversations
even if his cell phone is not in use. Under remote control, the mic can listen to sounds, the camera take pictures, and the audio of any incoming/outgoing call can be monitored in real time, without the cell phone owner knowing it. The software for this is widely available, and obviously can be used for non-parental situations:

Today every keystroke of workers can be monitored and compared to a database of work output and efficiency. Their phone calls, emails and text messages are monitored and analyzed.
As email replaces paper letters, privacy is potentially lost. Either a family member or a government agency can intercept the email via various methods.
The physical location of anybody with a cell phone can be monitored by law enforcement, without a warrant, and regardless of whether the phone has GPS:

Supposedly every cell phone call and email made by anyone on Earth can be intercepted by NSA satellites and the content evaluated by the Echelon computer network. No wiretap warrant is required for this since computers are doing the work, not people: http://en.wikipedia.org/wiki/Echelon_(signals_intelligence )
Increasingly sophisticated facial recognition software, coupled with ubiquitous public CCTV cameras allow tracking your movement.
Recent technological developments have made possible monitoring that George Orwell could not dream of when he wrote
1984.
It's misleading to think privacy in earlier eras was minimal, and people today are over-reacting. A farmer from 1800 would likely be horrified at the intrusive, invasive oversight possible today.
