Forms

Electronic media and print media include:

• Broadcasting, in the narrow sense, for radio and television.
• Various types of discs or tapes. In the 20th century, these were mainly used for music. Video and computer uses followed.
• Film, most often used for entertainment, but also for documentaries.
• Internet, which has many uses and presents both opportunities and challenges. Blogs and podcasts (such as news, music, pre-recorded speech, and video)
• Mobile phones, often called the 7th Mass Media, used for rapid breaking news, short clips of entertainment like jokes, horoscopes, alerts, games, music, and advertising
• Publishing, including electronic publishing
• Video games, which have developed into a mass form of media since cutting-edge devices such as the PlayStation 3, XBox 360, and Wii broadened their use.

Journalism

Journalism is the discipline of collecting, analyzing, verifying and presenting information regarding current events, trends, issues and people. Those who practice journalism are known as journalists.

News-oriented journalism is sometimes described as the "first rough draft of history" (attributed to Phil Graham), because journalists often record important events, producing news articles on short deadlines. While under pressure to be first with their stories, news media organizations usually edit and proofread their reports prior to publication, adhering to each organization's standards of accuracy, quality and style. Many news organizations claim proud traditions of holding government officials and institutions accountable to the public, while media critics have raised questions about holding the press itself accountable.

Public relations

Public relations is the art and science of managing communication between an organization and its key publics to build, manage and sustain its positive image. Examples include:

• Corporations use marketing public relations (MPR) to convey information about the products they manufacture or services they provide to potential customers to support their direct sales efforts. Typically, they support sales in the short and long term, establishing and burnishing the corporation's branding for a strong, ongoing market.
• Corporations also use public-relations as a vehicle to reach legislators and other politicians, seeking favorable tax, regulatory, and other treatment, and they may use public relations to portray themselves as enlightened employers, in support of human-resources recruiting programs.
• Non-profit organizations, including schools and universities, hospitals, and human and social service agencies, use public relations in support of awareness programs, fund-raising programs, staff recruiting, and to increase patronage of their services.
• Politicians use public relations to attract votes and raise money, and, when successful at the ballot box, to promote and defend their service in office, with an eye to the next election or, at career’s end, to their legacy.

Negative characteristics of mass media

Another description of Mass Media is central media which implies:

• An inability to transmit tacit knowledge (or perhaps it can only transfer bad tacit).
• The manipulation of large groups of people through media outlets, for the benefit of a particular political party and/or group of people.
• Marshall McLuhan, one of the biggest critics in media's history, brought up the idea that "the medium is the message."
• Bias, political or otherwise, towards favoring a certain individual, outcome or resolution of an event.
• "The corporate media is not a watchdog protecting us from the powerful, it is a lapdog begging for scraps."^[1]

This view of central media can be contrasted with lateral media, such as email networks, where messages are all slightly different and spread by a process of lateral diffusion.
