OK, you're probably right, it's just that a lot of people think that it's always been the way it is now, and I 
know, for example, that we still had DC mains supplies in some parts of Britain during my lifetime, and the 
current standards for sockets, wiring and so on, are all younger than I am (not that that's saying much! :-)

Yes, the other thing they don't touch on is Earthing, standards and practices of which vary more than voltages 
and frequencies do - including what it's called!  But for the purposes it's aimed at (tourists taking 
electrical appliances abroad with them) it does its job.
