They both have some interesting paralells, they both came with the idea of being a superior quality format, both had some new functions previously unseen, and both failed to get mass market point but still were relevant due to appealing for a niche group that praises quality.
Blu-Ray has more adepts than LaserDisc ever had, but, it is also a far cry from the kind of dominance DVD had. Blu-Ray never really " killed "DVD, with DVD movies were still selling more than their BD counterparts for years, and when things started to shift streaming came with everything and became the main way of watching HD home video.
BD is still alive and well as media for movies and TV shows, but thanks to enthusiasts that praise quality over anything. Because BD quality is far superior than streaming, for sure, but the practicity of streaming is unparalled.
And this answer the question, DVD didn`t win from VHS because it had better quality, but because it was more practical. People go for quality good enough and practicity, not super quality only.
Disclaimer: Posting this on Movies session because we are talking about media formats used mainly for movies consumption. I know I have this OCD of explaining why I put my thread at the sections that I put, but people on internet can make such a huge of thing of little things I prefer to certificate.
