Heavily the technology of hedonism and entertainment. This is when the VCR and the compact disc player, and eventually the DVD player, became cheap enough to be commonplace.
High fidelity came earlier, of course.
It is telling that there has been little innovation in the mass market for something so obvious as Blu-Ray, let alone 4K music fidelity. Blu-Ray can compress sound into really-convenient packages with little seeming loss. Maybe it is the recording business that frustrates change.
There were 2 competing optical formats around 1999 till the late 2000s that never really took off due to streaming and other issues: Super Audio CD from Sony and DVD-Audio from the DVD consortium (not to be confused with music DVDs which were just 'movie' DVDs with a concert or whatnot in lossy compressed audio). SA-CD had an advantage of its discs also being able to be manufactured to store standard CD content on them too. Both of these high res formats promised high resolution sound and multi-channel capability with no lossy compression needed to fit the content on a disc. My guess at why these formats failed was the experience of music already even as of 1999 becoming more of a portable/personal experience. There was no point in making multi-channel formats if people were listening in headphones on their way to work. Regarding the higher resolution, people can't hear past approx 20 KHz so a sample rate beyond the existing CD's 44.1 KHz made no sense. What's left? 24-bit dynamic range (CDs used only 16 bits). 24-bit stuck around into the current streaming era with some services offering it (Tidal).
