Another example is in news aggregation services, where users subscribe to specific topics and receive updates.

Can you give me more examples in technology?

Sure! In technology, the publish-subscribe model is used in event-driven architectures, such as in cloud services like AWS SNS (Simple Notification Service). It allows applications to send notifications to multiple subscribers efficiently. Additionally, social media platforms use this model to notify users about new posts or updates from accounts they follow.

What about in finance?

Are there any examples in IoT?
