What is Amazon's subscription service that offers free shipping and other perks?

Amazon’s subscription service offering free shipping and other perks is Amazon Prime.

Amazon introduced Prime in the United States in 2005 as a membership program built around unlimited two-day shipping for an annual fee. The idea was to encourage frequent shopping by making delivery costs predictable and giving members a reason to consolidate more of their purchases on Amazon.

The service later expanded into a broader bundle. Depending on the country and plan, Prime can include fast or free delivery, Prime Video, Prime Reading, Prime Gaming, member-only discounts, and access to selected music or photo-storage features. The exact benefits and prices vary by market, so Prime is not identical everywhere.

Amazon Web Services is a cloud-computing business, Amazon Music is a music-streaming service, and Amazon Fresh is a grocery offering; none is Amazon’s general membership program. Prime Video may be included with Prime, but it is only one benefit within the larger subscription. That distinction makes Amazon Prime the canonical answer.
