I never understood the product name anyway. To me Carbon Black was always a compound used in the industrial manufacture of rubber because it makes vulcanized rubber harder, stronger and more resilient which are obvioulsy desirable properties in rubber. Oh and it also makes the rubber black rather than a mucky brown colour which is apparently another desirable property in rubber products. Not sure why that is the case. I mean yes we're used to tyres (for example) being black but if your tyres weren't black would that make them any less desireable.
Getting to the point however...
Why choose a name for a fairly well known product used in the manufacture of rubber to describe a product for virtual machine computing? I mean there's no way VMware can claim they didn't know of the previous and widespread use of the term before they began marketing their product,
