Well, let's consider the various, mostly incompatible, phonograph
formats that have been used over time:

The Edison cylinder.

Various 78 rpm disks.

The 45 rpm mono disk.

The 45 rpm stereo disk.

The 16 rpm mono disk for audio books and radio transcription.

The 33 rpm mono disk.

Emory Cook's 33 rpm two-tonearm stereo disk

The 33 rpm stereo disk, one grove with 45-degree channels

The 33 rpm matrixed quad disk.

The 33 rpm dbx stereo disk.

The 33 rpm discrete quad disk.

"ubiquitous computer network" requires interoperability in a way that
records have never ever had.
