KK: /ˈroʊlˌaʊt/
The process of introducing a new product or service to the public, often involving a planned launch or rollout strategy.
The company announced the rollout of its new smartphone next month.
Rollout → It is formed from "roll" (from Old English "rollian", meaning to turn over or rotate) and "out" (meaning to extend or move outward). The word "rollout" refers to the act of rolling something out or introducing it in a gradual manner.
Think of something that is 'turning over' ('roll') and then 'extending outward' ('out') — that's how rollout means to introduce or launch something gradually.
