Introduction to broadcast journalism

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 Internet generally. Such media disperse pictures (static and moving), visual text, and/or sounds.
Scripts for speaking to be broadcast tend to be written differently than 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.
Broadcast "stories" (articles) can be written in "packages", "readers", "voice overs", and "sound on tape".
A "package" is an edited set of video clips for a news story and is common on television. It is narrated typically by a reporter. It is a story with audio, video, graphics and video effects. The anchor usually reads a "lead in" (introduction) 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 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".
