Question Type: Vocabulary/Definition

This question tests your understanding of terminology used in electronic commerce.

Step-by-step solution:

• The question describes a fixed sum paid regularly for a service.
• Let's analyze the options:
  • Licensing: Refers to granting permission to use software or intellectual property, not necessarily a recurring payment.
  • Affiliate: Relates to a marketing model where individuals or companies earn commissions by promoting products or services, not a fixed recurring payment.
  • Marketing: The process of promoting and selling products or services, not a specific payment model.
  • Subscription: A recurring payment model where customers pay a fixed fee for access to a service or product. This perfectly matches the question's description.
• Therefore, the correct answer is subscription.

Why other options are incorrect: Licensing, affiliate marketing, and general marketing describe business models or strategies, not a specific payment structure like the one defined in the question. Only ""subscription"" accurately describes a fixed, recurring payment for a service.
