Does anyone remember IBM's PS2, i.e. a new IBM PC with Microchannel and 32-bit architecture), except not called a PC because that term had quickly become generic)? OS/2 was the OS for the PS2. But ask anyone now what PS2 means, and most likely they'll have no idea. Wikipedia doesn't even go to a disambiguation page - just straight to the Sony Play Station 2. As for DB2, I'm not so sure. First came SQL/DS (on VM), and it was doubtless pure marketing speak to call the later MVS port DB2.
