Subscribers are individuals who sign up to receive content, updates, or services from a particular source, such as a website, newsletter, or streaming platform. They often provide their email addresses or create accounts to access exclusive material, promotions, or features. In the context of digital media, subscribers can be found on platforms like YouTube, Spotify, or Netflix, where they pay for premium content or follow creators for regular updates. This model helps content providers build a loyal audience and generate revenue through subscriptions.
