A news aggregator is a website, application, or service that collects and curates news content from multiple sources and presents it to users in a centralized location. This allows users to easily access a variety of news articles and sources without having to visit multiple websites or apps. News aggregators use algorithms to gather and organize content from various sources, including newspapers, blogs, social media, and other online news outlets. They also often provide customization options for users to select the types of news they want to see, such as topics or sources. Some examples of popular news aggregators include Google News, Flipboard, and Feedly.
