Content aggregators are platforms that collect and display content from various sources in one place. They help users discover articles, videos, and other media by curating information based on specific topics or interests. Examples of content aggregators include Feedly, Flipboard, and Google News. These tools save time by allowing users to access multiple sources without visiting each website individually. Content aggregators often use algorithms or user preferences to personalize the content feed, making it easier for individuals to find relevant information and stay updated on their favorite subjects.
