Saw this the other day. Looks like Samsung is scrapping their line of 4k Blu-Ray players, at least in the US.
Now we have Oppo and Samsung dumping the disc technology.

I remember the BetaMax vs VHS battle. BetaMax was a much better format. Although, it was a bear to do all the necessary alignments when they came in for servicing, I was sure that would have evolved over time.
Just like the first few generations of CD players. There were several adjustments that needed to be done, and each one affected the next to a degree. Striking a balance with all of them took some time.

Streaming services are taking over. More and more devices are hitting the market. Many of them are a bit buggy with audio formatting, video resolution settings and such. But like with all mass produced items, they'll throw them out there and let the consumer be the beta tester.
