A news aggregator is a tool or service that collects and displays news articles from various sources in one place. It helps users stay informed by providing a wide range of news topics, including politics, sports, and entertainment, all in a single feed. Popular examples of news aggregators include websites and apps like Google News and Feedly. These platforms often allow users to customize their news feeds based on their interests, making it easier to find relevant information. By gathering content from multiple publishers, news aggregators save time and help users discover diverse perspectives on current events.
