A streaming platform obtains contents from artists and offers commercial spaces to advertisers. Users value contents’ variety and quality of the service and are heterogeneously bothered by ads. Two solutions can be proposed to users. If they pay a positive price, they subscribe to a commercial-free service with an upgrade of quality (Premium). Otherwise, they have free access to a service of a basic quality. We find that a wider audience gives incentives to the platform to increase both the advertising intensity and the quality upgrade in the Premium. As a consequence, some people move to the Premium. At the limit, the platform opts for a purely subscription-based business model as the audience reaches a certain level. The parsimonious model we propose is able to give a rationale to the emergence of different business models in the streaming market as well as to the (end of the) disputes between artists and the Spotify model.

流媒体平台从艺术家那里获取内容，并为广告商提供商业空间。用户重视内容的多样性和服务质量，并被广告打扰。可以向用户提出两种解决方案。如果他们支付正价，则他们会订阅免费的服务，并会提高质量（Premium）。否则，他们可以免费使用基本质量的服务。我们发现，更广泛的受众为该平台提供了激励，以增加Premium的广告强度和质量提升。因此，有些人选择了高级版。当受众达到一定水平时，该平台将选择纯粹基于订阅的业务模型。我们提出的简约模型能够为流媒体市场中各种业务模型的出现以及艺术家与Spotify模型之间的（最终）纠纷提供理论依据。
