To roll out is to introduce or launch something new, typically a product or service, to the public or a specific target audience. This term is often used in the business world, where companies carefully plan and execute the roll out of their latest offerings in order to generate buzz and attract customers. It can also refer to the physical act of unrolling or spreading out a material, such as a carpet or dough. In both cases, the idea of gradually revealing or unveiling something is key, as a roll out is typically done in a strategic and deliberate manner.
