'Wow' is Scottish in origin. It appears in the poems of Allan Ramsay the poet (1686–1758) and of Robert Burns as in "And, wow! Tam saw an unco sight!" - 'Tam o' Shanter' poem. The word is probably a contraction of the interjection 'I vow!'. The word travelled to America where it took root and returned to the U.K. probably in the 20th century. (Wiktionary)
