Broadcast journalism is the field of news and journals which are "broadcast", that is, published by electrical methods, instead of the older methods, such as printed newspapers and posters. Broadcast methods include radio (via air, cable, and Internet), television (via air, cable, and Internet), and, especially recently, the World Wide Web. Such media disperse pictures (static and moving), visual text and/or sounds.Scripts for speaking to be broadcast tend to be written differently from text to be read by the public. For instance, the former is generally less complex and more conversational. Radio and television are designed to be seen and heard sooner and more often than is a daily or weekly newspaper.DescriptionBroadcast "stories" can be written in "packages", "readers", "voice-overs" and "sound on tape" .A "sack" is an edited set of video clips for a news story and is common on television. It is typically narrated by a reporter. It is a story with audio, video, graphics and video effects. The news anchor, or presenter, usually reads a "lead-in" before the package is aired and may conclude the story with additional information, called a "tag".A "reader" is an article read without accompanying video or sound. Sometimes an "over the shoulder Digital on-screen graphic" is added.A voice-over, or VO, is a video article narrated by the anchor.Sound on tape, or SOT, is sound and/or video, usually recorded in the field. It is usually an interview or "soundbite".RadioRadio was the first medium for broadcast journalism. Many of the first radio stations were co-operative community radio ventures not making a profit. Later, radio advertising to pay for programs was pioneered in radio. Later still, television displaced radio and newspapers as the main news sources for most of the public in industrialized countries.
