Pressing CDs was expensive, which worked for the audio mass market, but not for the PC niche market. That limited the appeal of buying an (expensive) CD drive, and they weren't even using a standard protocol (so: lots of issues). When CD creation became cheaper and the market grew, the economies started to work out in the mid-90s, until the late-90s saw computer mags with cover-CDs (a signal that everybody in that market had CD drives, and pressing CDs was cheap enough for one-off low-count productions like that)
