Television

I mean, iirc, Blu-ray was originally Sony's thing; VHS was JVC. Most formats were something a company came up with and then became so widely used that people thought they just sprung out of the ether.

The multi-terabyte disc thing sounds neat. Project Silica is the sci-fi crystal data cube thing, where they vaporize tiny bits of crystal with a laser to write data, and then read it back with a laser as well. I like the idea of project silica more just because "muh sci-fi data cubes", but discs capable of holding terabytes of storage would be sweet.
