==History==

In 1996, [[NetMind]] developed the first change detection and notification tool, known as Mind-it, which ran for six years. This spawned new services such as ChangeDetection (1999), ChangeDetect (2002), [[Google Alerts]] (2003), and Versionista (2007) which was used by the [[John McCain 2008 presidential campaign]] in the race for the [[2008 United States presidential election]].<ref>{{cite web |title=To the Wayback Machine, Sherman!|url=https://www.economist.com/democracy-in-america/2008/07/16/to-the-wayback-machine-sherman |publisher=[[The Economist]] |accessdate=9 January 2019}}</ref>. Historically, change polling has been done either by a server which sent email notifications or a desktop program which audibly alerted the user to a change. Change alerting is also possible directly to mobile devices and through [[push notification]]s, [[webhooks]] and HTTP callbacks for application integration.

Monitoring options vary by service or product and range from monitoring a single web page at a time to entire web sites. What is actually monitored also varies by service or product with the possibilities of monitoring text, links, documents, scripts, images or screen shots.
