What is AP Style?
AP Style (a.k.a. Associated Press Style) provides guidelines for grammar and citations in news writing. It's the style guide most newspapers, magazines, and other media outlets use, so this style is a must-have for anyone who wants to work in journalism or media writing.
History of AP Style
The Associated Press was founded in 1848 by six New York newspapers who desired to share resources for international news. The newspapers saved money by sharing the news that arrived by telegraph wire and dividing the expenses evenly; this prevented competition for information. The AP is currently the largest news gathering organization in the world and uses its style to keep the news easy to read, concise and free of bias. First published in 1977, The Associated Press Stylebook lists the rules regarding grammar, spelling, punctuation and usage. The Stylebook is the standard guide for most U.S. newspapers, magazines and other media.
