Yep, Blueray was a drummed up fad with no real need for it.
A drummed up fad with more content, picture/audio encoding is uncompressed (Most of the content even when compressed higher quality than streaming), higher bit rates, Internet restrictions, no need to find content where the future will be needing a separate subscription service for Nextflix, Hulu, the Disney’s service that is coming, whatever Movie studio wants to secure their own service/IP, etc... each month, some people like the special features as well.
Not much of a fad if you ask me especially if the top movies of the year are still pushing over 1-4 million units sold (BR) in the US in the age of easy pirating and streaming options.
