In the United States, Amber alerts are distributed via commercial and public radio stations, Internet radio, satellite radio, television stations, text messages, and cable TV by the Emergency Alert System and NOAA Weather Radio (where they are termed "Child Abduction Emergency" or "Amber Alerts"). The alerts are also issued via e-mail, electronic traffic-condition signs, commercial electronic billboards, or through wireless device SMS text messages. AMBER Alert has also teamed up with Google, Bing, and Facebook to relay information regarding an AMBER Alert to an ever-growing demographic: AMBER Alerts are automatically displayed if citizens search or use map features on Google or Bing. With the Google Child Alert (also called Google AMBER Alert in some countries), citizens see an AMBER Alert if they search for related information in a particular location where a child has recently been abducted and an alert was issued. This is a component of the AMBER Alert system that is already active in the US (there are also developments in Europe). Those interested in subscribing to receive AMBER Alerts in their area via SMS messages can visit Wireless Amber Alerts, which are offered by law as free messages. In some states, the display scrollboards in front of lottery terminals are also used.
