'promotion-centered' originates from the English word 'promotion,' which comes from the Latin word 'promotio,' meaning 'advancement,' and 'centered,' which is derived from the Latin 'centrum,' meaning 'center.'

'promotion' evolved from the Latin 'promotio' through Old French 'promotion,' and 'centered' evolved from the Latin 'centrum' through Old French 'centre.'

Initially, 'promotion' meant 'advancement in rank or position,' and 'centered' meant 'having a center.' The combined term 'promotion-centered' now refers to a focus on promotional activities.
