Internet change detection and notification (CDN) refers to automatic detection of changes made to World Wide Web pages and notification to interested users by email or other means. Whereas search engines are designed to find web pages, CDN systems are designed to monitor changes to web pages. Before change detection and notification, it was necessary for users to manually check for web page changes, either by revisiting web sites or periodically searching again.
[edit] History
In 1996, NetMind developed the first change detection and notification tool known as Mind-it which ran for 6 years. This spawned new services such as ChangeDetection.com (1999), ChangeDetect (2002), Google Alerts (2004) and others.
