Sears tv

Sears sold this console tv for $750 back in 1964. But stated in the value of our current U.S. dollars, that sum would today be $5,800. 

A tv costs us much, much less today in terms of hours of work required to pay for it. A tv today is also light years ahead in terms of picture, sound and programming.

Innovation in every related industry is part of the reason. Global trade across borders is another part of the reason.
