Google Alerts is a content change detection and notification service, offered by the search engine company Google. The service sends emails to the user when it finds new results—such as web pages, newspaper articles, blogs, or scientific research—that match the user's search term(s). In 2003, Google launched Google alerts which were the result of Naga Kataru's efforts. His name is on the three patents for Google Alerts.
