purposes of mass media :
Mass media encompasses much more than just news, although it is sometimes misunderstood in this way. It can be used for various purposes:
*Advocacy, both for business and social concerns. This can include advertising, marketing, propaganda, public relations, and political communication.
*Entertainment, traditionally through performances of acting, music, sports, and TV shows along with light reading; since the late 20th century also through video and computer games.
*Public service announcements and emergency alerts (that can be used as political device to communicate propaganda to the public).
