Actually, many people are junking perfectly good 'large screen' CRT TVs when most of what they watch will be SD not HD (so few HD channels with naught but crap!) anyway! :-) - And since those CRTS (with set top boxes) are still usable for a good many years, it is just an enormous waste of money and used resources.

Forget '3D' too - it just gives me a headache, and makes me think of watching an old multilayer 2D (flat pictures drawn on cards) puppet theatre...

Of course, the Capitalists WANT us to junk stuff that works so they can make more money with new stuff - just like cars too...

First, get that antenna and lead in upgraded... then think about a new set a while later - spreads the load out ...
