Something I haven't seen mentioned, the TV's got a lot lighter too. That's purely anecdotal from me having had to move TV's around for the past few decades, and that's not comparing CRT's to LCD's. Even the LCD's have become lighter.

I'm assuming it's a function of building the devices down to a price point. Fewer atoms makes for lower cost.

I look at some large TVs of 2016 vintage being sold for surplus and I was shocked at how heavy they were. I don't have the specific numbers handy, but I recall they were >40 lbs heavier than I expected them to be compared to today's TVs.

Coming from rear-projection TVs as a kid to 75"+ TVs I can pick up with one hand is still super surprising to me

Definitely noticeable and inversely correlated with the quality of native sound from the average LCD/LED TV nowadays - putting sufficient wattage speakers and optimising for audio with acoustic cavities became an afterthought once soundbars were accepted as a necessity. Cooling systems are also greatly improved.

This also helps with the cost, as shipping costs are partially based on weight.
