I don't think Sony "gave up" on SACD....more like they pulled back their efforts once the mass market rejected SACD. Sony still owns and operate 2 of the 3 SACD pressing facilities in the world (in Austria and Japan) and regularly releases new SACDs in Japan directly through its music division. In the US, instead of releasing SACD titles directly through its music division, Sony license its music for release on SACD through audiophile labels such as Mobile Fidelity, Analogue Productions, and the now-defunct Audio Fidelity. Given its niche status, it's surprising SACD has last over 20 years.
