Vinyl was basically passe for quite a while (outside of the DJ crowd), but experienced a resurgence in recent years as people discovered the qualities of analog audio, with new turntables widely available in both low and extremely high quality, and everywhere in between.
As higher-definition video formats eventually overtake the old ones, I think blu ray may someday be more analogous to something like LaserDisc.

I think people will still be using VCR's/DVD-recorders for years to come. I know a few people who are on OTA Antennae, and whle they've bought a digital converter, there were very few stand-alone DVR/PVR's, and from what they told me, most of the reviews that they could find mentioned that people had a lot of trouble with them. So there are still people using a VHS and DVD-recorder to "time shift" their programming in standard-definition.
But I think that right now Blu-Ray is already analogous to the Laser Disc, as, while it does have a larger install base, it doesn't have the same base as DVD, and there are many more titles being released on DVD than on Blu-Ray, even when it comes to new releases. Even when I go into stores, the newest movies tend to have more DVD copies than Blu-Ray copies. Even TV shows produced during the era of HD TV see very few being released on Blu-Ray, or in the case of Smallville, only see partial releases. With Smallville. Warner's has said that Seasons 2-5 were done in HD, but aside from Season 5 appearing on the HD-DVD format (but not on Blu-Ray), there has been no Blu-Ray reissue. So I think Blu-Ray's days are numbered, plus I've been noticing how studio's are releasing movies and TV shows on digital before they release the physical media.
As for Fuani's 750,000, that has been from the sale of VHS/DVD combo units. There have been no stand-alone VCR's made since 2008.
