Newspapers have attempted to integrate the internet into every aspect of their operations, i.e., reporters writing stories for both print and online, and classified advertisements appearing in both media; others operate websites that are more. Mass media denotes a section of the media specifically designed to reach a very large audience such as the population of a nation state. The term was coined in the 1920s with the advent of nationwide radio networks, mass-circulation newspapers and magazines. However, some forms of mass media such as books and manuscripts had already been in use centuries. The term public media has a similar meaning: it is the sum of the public mass distributors of news and entertainment across media such as newspapers, television, radio, broadcasting, which may require union membership in some large markets such as Newspaper Guild, ASTRA, and text publishers. Mass media includes Internet media (like blogs, message boards, podcast, and video sharing) because individuals now have a means to exposure that is comparable in scale to that previously restricted to a select group of mass media producers. The communications audience has been viewed by some commentators as forming a mass society with special characteristics, notably atomization or lack of social connections, which render it especially susceptible to the influence of modern mass-media techniques such as advertising and propaganda. Internet is the system of interconnected computer networks, linked by copper wires, fiber-optic cables, wireless connections etc.; the Web is the contents, or the interconnected documents, linked by hyperlinks and URLs. The World Wide Web is accessible through the Internet, along with many other services including e-mail, file sharing and others described below.Toward the end of the 20th century, the advent of the World Wide Web marked the first era in which any individual could have a means of exposure on a scale comparable to that of mass media. For the first time, anyone with a web site can address a global audience, although serving to high levels of web traffic is still relatively expensive. It is possible that the rise of peer-to-peer technologies may have begun the process of making the cost of bandwidth manageable. Although a vast amount of information, imagery, and commentary (i.e. "content") has been made available, it is often difficult to determine the authenticity and reliability of information contained in web pages (in many cases, self-published). The invention of the Internet has also allowed breaking news stories to reach around the globe within minutes. This rapid growth of instantaneous, decentralized communication is often deemed likely to change mass media and its relationship to society."Cross-media" means the idea of distributing the same message through different media channels. A similar idea is expressed in the news industry as "convergence". Many authors understand cross-media publishing to be the ability to publish in both print and on the web without manual conversion effort. An increasing number of wireless devices with mutually incompatible data and screen formats make it even more difficult to achieve the objective “create once, publish many”..duplication of information for the first time.
