Despite the audiophilia-disposition of the video, my personal observation has been that DJs and audiophiles have kept the industry in motion. I personally continue to collect vinyl, because I actively play vinyl. It's a heartache when a venue doesn't have turntables, but I do have Serato to keep me in the game. But I digress.
I'd be curious to know what the conversion rate of newbie-djs-with-digital-tools-to-vinyl is. With such ubiquitous technologies for emulating turntables (and jesus poses!), it seems feasible that a wider market share of DJs contributes to vinyl's extended lifespan.
