My mother in law died last summer aged 92. Last XMass her children got together and purchased for her an LG TV because her current one had died, and she spent a considerable amount of time in her dotage watching programs like The Crown.
Several of us were staying with her during the Holiday so we set it up and damn, the hardest part was actually operating the software. Not only did it completely flummox mom but the rest of us in our sixties were also struggling. We are mainly Physicians, Nurses, Lawyers, and an engineer for the FAA.. Fortunately our 24 year old Niece was with us and for her it was all intuitive; she spent the bulk of her Holiday visit giving us all tutorials.
Mom really enjoyed her TV during her last few months with the various streaming services at her option, but perhaps the manufacturers should put a basic option on the software package that most alte cockers can use and avoid 99% of the features that just complicate the daylights of general usage
