In its annual Theatrical Home Entertainment Market Environment report, the
Motion Picture Association of America described an immensely sharp drop-off of physical media sales over the past five years. According to the data, which was obtained from DEG and IHS Markit, global sales of video disc formats (which in this context means DVD, Blu-ray, and UltraHD Blu-ray) were $25.2 billion in 2014 but only $13.1 in 2018. That's a drop in the ballpark of 50 percent.
Don't expect 8K Blu-rays or other emerging quality-focused formats to turn the tide, either. Market data published by
Forbes showed that the aging, low-definition DVD format still accounts for 57.9 percent of physical media sales, and
4K Blu-rays are only 5.3 percent.https://arstechnica.com/gadgets/2019/04/dvd-and-blu-ray-sales-nearly-halved-over-five-years-mpaa-report-says/
