A:Answer There will be new models coming out every year, from all manufacturers. Generally, the manufacturers show off and release their new year's models to the public, at CES (Consumer Electronics Show,), in las Vegas, in early January, and, usually, they begin showing up at retailers in March or April.
Occasionally the manufacturers unveil revolutionary new technology , such as LG's OLED displays, or Samsung's QLED technology, but, generally, there are usually minor, incremental upgrades, from year to year, such as, possibly an increase in brightness levels, updates to the Dolby software, or a revamped remote control unit, etc., among all features.
So a buyer of a 2016 model year TV isn't likely to see a drastic difference between their new set and a comparable, newer 2020 model year TVs released this year. But, over the course of five to 10 years, there is likely to be significant changes and upgrades, as well as the likelihood of substantial price drops, to make the purchase of a new TV, a tempting choice, even if the current TV is still functional.
