'advertising-centric' originates from the combination of 'advertising' and the suffix '-centric', where 'advertising' refers to the activity of promoting products or services, and '-centric' means 'centered around'.

'advertising' comes from the Latin word 'advertere', meaning 'to turn towards', and '-centric' is derived from the Greek word 'kentrikos', meaning 'pertaining to a center'.

Initially, 'advertising' meant 'to turn attention towards', but over time it evolved into its current meaning of 'promoting products or services'.
