Samsung gives up on Blu-ray players in the U.S. February 16, 2019 https://mashable.com/article/samsung-wont-sell-blu-ray-players-in-united-states/
I don't believe it is competition or a standards war. It is Sony greed. Sony owns Blu-ray. So if Samsung, LG, Panasonic, Microsoft, Nintendo, or who ever wants to build a Blu-Ray player or put Blu-Ray support in their products, they have to pay Sony licensing fees. This is exactly why Blu-ray support is NOT built into Windows - Sony would charge MS for every single license and that, in turn, would raise the cost of each Windows license.
I must say that I prefer streaming over DVD, I absolutely hate it that you can not always skip commercials in the beginning of DVD's.
