'rollout' originates from the combination of 'roll' and 'out', where 'roll' meant 'to move by turning over' and 'out' meant 'from inside to outside'.

'rollout' evolved from the literal action of rolling something out, like a carpet, to its modern metaphorical use in business and technology.

Initially, it meant 'to physically roll something out', but over time it evolved into its current meaning of 'introducing a new product or service'.
