Thompson/Tomson/Thomson
Veering slightly off topic, but it just goes to show that the marketing men don't have total control. 'Britannia' was apparently dropped because the focus groups decided that nobody could spell Britannia in search engines. They also decreed that Thompson was too hard to spell, so called it Tomson ( or was it 'Thomson'?) But even they can't change basic English, and in the minds of most English speakers it remains THomPson.
