promo

The term 'promo' is a 20th-century clipping of the word 'promotion', which itself entered English in the late 14th century from Old French 'promotion', meaning "advancement in rank or position". This Old French term derived from Latin 'promotionem' (nominative 'promotio'), a noun of action from the verb 'promovere', meaning "to move forward, advance". The verb is composed of 'pro-', meaning "forward", and 'movēre', meaning "to move". The specialized commercial and advertising sense of "promotion" developed in the 1920s, and its clipped form 'promo' emerged later in the century as a casual, industry-specific term for advertising material, thus moving from a general concept of advancement to a specific, modern marketing tool.
