Journalism involves writing news reports, articles, and other pieces for newspapers, magazines, television, radio, and online. It aims to inform readers and viewers about current events. There are several types of journalism, including advocacy journalism which promotes particular issues, broadcast journalism which is published electronically, investigative journalism which uncovers hidden information, tabloid journalism which focuses on gossip and sensational stories, and yellow journalism which uses exaggerated claims and headlines to sell more papers. Journalism can be used as a tool for social justice but can also spread propaganda when not carefully practiced.
