Apparently, the Snickers / Marathon name has a history. Snickers was the name of a horse and was chosen as the name for a chocolate bar. (1929)
It was an esoteric choice of name, but in the UK the bar was given the name 'Marathon'.
Re-branding to the original 'Snickers' name in 2008 because on the continent of Europe they (like the US) were more familiar with that name.
