The MPMC comprised companies including Microsoft, Creative Labs, Dell, Gateway, and Fujitsu.
CD-ROM drives were just coming to market in 1990, and it was difficult to concisely communicate to a consumer all the hardware requirements for using "multimedia software", which mostly meant "displaying video synced with audio on a PC via a CD-ROM drive".
The MPC program had mixed results primarily because of the vast number of PCs sold under different brands, and once Windows became ubiquitous on PCs, specifying minimum or recommended Windows versions and features was often clearer to consumers than the MPC nomenclature.
The problem of software labeling continues, especially in the field of computer games, where a multitude of 3D video cards has been manufactured with an extremely wide range of capabilities, and no common industry labeling standard to let consumers know whether their card is powerful enough to run a particular game.
No further specification beyond MPC Level 3 in 1996 was published; the Multimedia PC Marketing Council dissolved not too long afterward.
