Communication is the process of sharing ideas, information, and messages with others in a particular time and place. Communication includes writing and talking, as well as nonverbal communication (such as facial expressions, body language, or gestures), visual communication (the use of images or pictures, such as painting, photography, video, or film), and electronic communication (telephone calls, electronic mail, cable television, or satellite broadcasts). Communication is a vital part of personal life and is also important in business, education, and any other situation where people encounter each other.
Businesses are concerned with communication in several special ways. Some businesses build and install communication equipment, such as fax (facsimile) machines, video cameras, CD players, printing presses, personal computers, and telephones. Other companies create some of the messages or content that those technologies carry, such as movies, books, and software. These companies are part of the media or telecommunications industries. Organizational communication is important in every business. People in organizations need to communicate to coordinate their work and to inform others outside the business about their products and services (these kinds of communication are called advertising or public relations).
