Content feeds are streams of information that deliver updates, articles, videos, or other media to users in real-time. They are commonly used on social media platforms, news websites, and apps to keep users engaged with fresh content tailored to their interests. These feeds can be personalized based on user preferences, allowing for a more relevant experience. For example, platforms like Facebook and Twitter utilize algorithms to curate content feeds, showing users posts from friends, trending topics, or articles related to their previous interactions.
