Blu-ray hits 20 years old, and it isn't dead yet — optical disc format was introduced to the public at CES 2006

Blu-ray technology was introduced to the public at CES in 2006, boasting improved density and capacity compared to DVDs due to advancements in laser diode technology. Despite facing competition from HD DVD, Blu-ray emerged victorious with its superior capacity, integration, and support. Over the years, Blu-ray has evolved with features like 4K resolution and HDR, maintaining relevance among home cinema enthusiasts. However, industry trends, such as the decline in physical media support from console makers, signal a potential decline in Blu-ray's future. Despite this, collectors and regions with limited bandwidth continue to sustain the format.
