maybe i should have said, just because one brand gets rid of connection or calls them legacy, doesnt mean the whole planet is doing the same.
"'
Is' doing the same"? As in this very day? No. Will eventually? Yes.
Can you find any, even one currently manufactured TV that supports S-Video? Analog VGA? Even the not-too-old DVI? And if you do find one, does it make moot the whole point when the vast majority of the 100s of other currently produced TV lack those ports?
its clearly not because of the lack of space
Of course it is! Look at the back of your computer. Even if you have a monster, "full tower" case, the rear panel I/O area is a small, defined, finite space. Now look at brand new motherboards - particularly those that support integrated graphics. See any VGA or DVI ports? Probably not. Why? Because there's no space due to being filled with HDMI, DisplayPort, various USB ports, Audio ports, Ethernet and more.
What is a TV today but a computer with a big monitor attached and an included tuner? All the connections must go into a defined, finite space near where that computer electronics is
OR the manufacturer must use wiring harnesses and long cables to "remote" locations somewhere else on the case - adding to the costs already strained by cutthroat completion.
Let me quickly add there is a HUGE "technical" reason to make every effort to avoid long cables too. And that is to prevent, eliminate and suppress
EMI/RFI emanating from the those wires in the TV interfering with other nearby electronics, and to prevent, eliminate and suppress
EMI/RFI from other nearby electronics interfering with that TV's electronics. I note the FCC, the 27 country EU MRA, and other global regulatory agencies take a very dim view of EMI/RFI emissions.
even the latest tvs from sony have analog/composite in and headphone out.
Now come on! Don't be silly.
OF COURSE, if the TV has built in speakers (including a headphone jack), it must have DAC circuitry and associated analog electronics. Why? Because sound (as in acoustic waves traveling through the air)
is analog. Period! End of discussion.
the global switch to a different type of refrigerant to prevent damage to the planets atmosphere/global warming, or that your system is almost 3 decades old and had damage,
has ZERO to do with "legacy" on electronics.
I never said it did. Come on, Waldorf! Open your mind and remove your blinkers. You have tunnel vision. Or just being argumentative again. Or both.
This is not hard to see. I was clearly illustrating with AC refrigerant, 3G/4G cell phones, and CD players in cars that support for legacy products ends in all sorts of industries - not just TV or computer electronics. Sorry you could not (or just refuse to

) see that, or how it correlates to computer and TV technologies too. But they do.
Just because eco-friendly laws forced the change of refrigerates, that does not mean older ACs or their refrigerants did not become "legacy" products. They did. There are many reasons something can become a legacy product other than simple advances in the state-of-the-art. Building codes, new safety regulations and new laws force such changes all the time.
I think you said it right: older folks.
As an "old folk", I don't see it that way - most of the time. Forget the fact I still have a landline - that's for a different discussion

.
I believe with age comes wisdom. That includes how to wisely spend (and save) our money. It simply is counterintuitive to get rid of something that is still working perfectly fine and serving its purpose. Yet that is exactly what many advances in these technologies require us to do. How many of you (including me) retired perfectly good CRT TVs for LCD? 4:3 LCD monitors for 16:10 or 16:9?
I have over 600 music CDs. I have "burned" copies of all to my cell and microSD. But did you know you cannot legally make a digital copy unless you have the original CD? Or more importantly, if you make a copy and decide to get rid of the CD you MUST get rid of all your copies too? Same with DVD/Blu-ray movies.
How many "younger folks" insisted their PlayStation 4 was no longer any good because the PS5 was out? How many will do the same again when suddenly, in 2026 (if rumors hold true) their PS5 and all their PS5 games will instantly become pieces of sh!t because PS6 is out? It is not just an "older folks" thing.
