ad-supported

The term is a modern compound adjective formed in the late 20th century within the context of media and digital business models. Its first element, 'ad', is a clipped form of 'advertisement', which itself originates from the Latin verb 'advertere', meaning 'to turn one's attention to'. The core component, 'support', derives from Latin 'supportare', meaning 'to carry or bear', which evolved into the English sense of providing the means for something to exist or continue. The suffix '-ed' converts the verb phrase into an adjective, describing a state of being financially upheld. Thus, the literal construction "advertisement-carried" logically evolved to describe any service whose operational costs are borne by advertising revenue, creating a clear contrast with subscription or purchase-based models.
