The old TV are not useless in this digital age. If you have a Digital Converter Box (about the size of a thick paperback book) it converts the digital signal to analog. I have two hooked up to old VHS players. I have Gigabit Internet, but I do not want Cable TV (too many channels…). Most channels (actually the vast majority of them) we have no interest in and the channel guide is so slow, by the time you look through it, most of the program is over… But I digress…
I also have an 18-foot Beam Antenna in my attic and I pick up over 75-digital channels and it feeds to a splitter that feeds our digital TVs and it feed the Digital Converter Boxes on the VCRs so we can still record off the digital network.
I also have a Roku Streaming device on each TV and they bring in hundreds of more channels off the internet and I also have a Tablo Digital Video Recorder to record the digital channels…
But the real disadvantage with the old TVs were lower picture quality and they warmed up any room from the heat generated from its electronics and they were a lot more expensive to run. Small CRT TV used about 80 watts and the large ones used as much as 250 watts an hour…
So, if you use the DVD player much, it would pay to buy one of the many good ones at thrift shops for as little as $2-5.00.
In a way you are right, but you could not be more wrong about the reasons… I will not argue the “Planned Obsolesce” of modern manufacturers…
But Digital TV offers significantly better picture and sound quality, more channel capacity through multicasting (that is where broadcasters can send supplementary digital channels on their existing broadcast signal, which can be seen in digital sub-channels; for instance Channel 14.1, 14.2, 14.3, etc…)
However; the global shift to digital was driven by these technical advantages, especially the efficient use of spectrum to deliver more services, the ability to offer high-definition content, and the eventual phase-out of older, less efficient analog technology.
There is only so much spectrum (the frequencies available for TV, Radio, etc…) if you want more information on this, Google it…
As more and more “things” use the available spectrum, the more and more crowded it becomes. Just to name a few of the things using the available spectrum are: mobile phones/cellular networks (3G, 4G, 5G), Wi-Fi and Bluetooth, satellite communications (GPS, TV, weather), and emergency services (police, fire, medical).
