Ted talks about how concerned he was for his viewer and his child. He talks about a gadget called collusion. Websites track you everyday based on the sites that you visit. These sites start tracking you, what collusion does is lets you view who is tracking you and allows you to stop and block the unwanted sites that may track you. Above is a picture that shows collusion. The blue sites are the sites you have visited the red is sites that have started tracking you off the sites you have been to, the grey is an unknown site that may be tracking you.
