Amazon Prime reminds me of how the telecommunications industry sell services. They have customers signed up to a bundle of services like: landline, mobile, cable/satellite TV and broadband.

If the customers don't want TV they are put on a free tier rather than being cancelled, so they are still officially a TV subscriber and can boost the viewing figures for the service.

It's useful to be vague if you are in a dying industry or your competitors are better established.
