Mass media affects public opinion by making it possible for large groups of widely dispersed people to develop collective attitudes regarding public affairs; mass media tells people what issues are important and motivates the public to action. Exposure to media activates people's convictions or causes them to form new ones. As a result, those who control the mass media have the capacity to sway public opinion.
