About 1974 I bought my first color TV — 19” RCA portable. It cost $500.
In 2008 I bought my first widescreen LCD — 32” VIZIO. It cost $750.
I have been checking prices on 50” 1080p and 4k TVs. They cost between $400 and $600 for several VIZIO models. Other brands are in the $300 range and the upper end TVs are in the $800 range.
We just bought a 40 inch LG 1080p TV for mrs riverdawg’s craft room for $250. Essentially the same TV cost us over $400 four years ago when we replaced our main TV in the den.
The question is how much of the lower cost of electronics today is due to virtual slave labor costs in China et al and how much is due to improvements in technology and automation or differences in environmental or other regulations on manufacturing.
