en.wikipedia.org/wiki/Holographic_Versatile_Disc - This one floundered and died before coming to market

en.wikipedia.org/wiki/3D_optical_data_storage - A bunch of different solutions, and it looks like they were all being developed independently circa 2008, and then went nowhere

My guess is that there’s not much use case beyond archival backups. That’s not going to get the economies of scale that CDs/DVDs/Blu-rays have. It’d be priced for the corporate market, but they already have perfectly good archival backup solutions. You’d also have to prove that it can be durable for at least a few decades, but even for commercial duplication, previous optical formats are just OK at best on longevity.
