The MNO convention for the number 6 comes from the US. Paradoxically, old US dials also have the word Operator round the number zero, so effectively there were two Os on the same dial.
The GPO decided that it made more sense for UK dials to have the O in the 0 position.
(The practice of dialling 0 for the operator stopped with the introduction of Subscriber Trunk Dialling because the 0 was used as the first digit of all dialling codes, as today, and the Operator number changed to 100.)
Now that phones are manufactured that can be used anywhere in the world, only one system can be used and, surprise, surprise, the US method prevailed!
