Final answer:
Freemium is the business model of giving away recorded music and letting consumers decide how and when to pay for it. In the radio and satellite radio industry, the subscription model is more commonly used.
Step-by-step explanation:
The business model of giving away recorded music and letting consumers decide how and when to pay for it is called freemium. Freemium is a combination of the words free and premium, and it refers to a business model where the basic version of a product or service is offered for free, while additional features or content are available for a fee.
An example of freemium in the music industry is a streaming service that offers a free version with limited access to music, but also offers a premium subscription for ad-free listening and access to a larger music library.
In the context of the given information about radio and satellite radio companies, the subscription model is more applicable, as it involves charging a regular fee for a specific service or content without the need for advertising.
