Telephone talks, letters, electronic mail, and audio and video cassettes are all examples of interpersonal mediated communication. Telephone calls, for example, can be considered a form of mediated communication because they allow two people who would not otherwise have contact to do so. In addition to individuals, organizations also use mediation to communicate with each other. Organizations use media such as newsletters, e-mail lists, websites, and social networking sites to communicate information about themselves and their products/services. As with individual-to-individual communication, there are benefits and costs associated with using media to communicate. Benefits of mediated communication include the ability to reach a large audience quickly, at little or no cost, and with no physical presence required. Mediated communications allow organizations to inform, recruit, sell products/services, and connect with consumers in ways that might be difficult or impossible face-to-face. Costs of mediated communication include time spent preparing and writing messages, ensuring their quality, and responding to comments from recipients. In addition, people have to make a decision regarding whether to listen to others or to focus on their own thoughts and feelings. Spending time listening to others may be beneficial, but cannot always be done through communication channels.
