Listened to an older 99% Invisible podcast this morning on the rise and fall (and preservation) of GeoCities…maybe one of the first consumer-oriented WWW platforms. Bought by Yahoo and started to fall apart after dot-com crash.
Betamax and HD-DVD, though Beta did live a long life behind the scenes of video production. Every hi-fi digital/streaming music standard post-mp3. Gesture-based user interfaces beyond simple swiping (e.g. Minority Report style interfaces.)
One might still see ‘Allsop’ or Softride products around PNW outdoorsy activities, like sweet shock-absorbing ski poles. Its a Bellingham thing!
They did try to make it a ‘platform’ but didn’t really catch on. Biopace was similar I guess, although the idea of non-round chainrings has persisted in other forms.
I was going to suggest Whitworth standard threads and measurement, but its not a total failure and aspects of it still are used in some industries.
The gesture control idea also lives on - one of the solid state engines that drove the tech was manufactured by Gyration, we did some mice and pointing devices for them at IDE Inc.
Another tech thing we worked on was a projected keyboard intended originally for use in PDA’s. The tech ended up getting rolled into Kinect… which is now gone.
