Probably because A and B are used for so many other things. The TV
convention of calling them domestic and GPO worked just fine in the

I wonder why you call them "domestic", when stereo
or balanced line on jack is rarely found on domestic
equipment - headphone outputs being the exception.

They were used as balanced mic inputs on high end domestic tape recorders
- before the days of stereo. And on some semi pro mixers or amps. The sort
you might find in a dance hall. But not on any pro gear.

In music we use the term "balanced jack" (add plug, if you like:-)
when it is obvious you don't mean a patchbay (GPO) type.

GPO is rather less of a mouthful than 'balanced jack'. And in TV we are
used to doing things at some speed - unlike the leisurely approach of the
recording studio.
