As the world prepared for the twenty-first century, electronic media—particularly computers and satellites in space—altered the nature of mass media organizations, world news, and traditional government internal information controls. Because one satellite can cover a third of the globe, its messages and images ignore national boundaries and thus radically alter the historic balance of power between nation–states and media corporations. Media entrepreneurs, like individuals, can operate outside of their national home bases in relative independence of governmental control.
Two additional developments have altered government-versus-corporation relations. Increasingly, a single, large multinational media corporation can control the entire communications system from creation of content to distribution and delivery to home or office. It does this by ownership of newspapers, magazines, radio, television, books, motion pictures, videocassettes, production facilities for all these media, as well as national and international distribution networks and control of the telephone or satellite dish that brings media material into individual homes. The other change is digital techniques that permit conversion of material from one form into a different one, like a motion picture into a videocassette playable into individual homes or over a television station.
Media power and profit have encouraged large firms to acquire as many different media as possible under each major firm's control. Thus, for example, at the turn of the century, a German firm, Bertelsmann, controlled 10 percent of all world publishing in the English language. Similarly, News Corporation, an Australian firm owned by an American, Rupert Murdoch, became a major media producer worldwide, including in the United States. Major American firms like Disney, AOL Time Warner, Viacom, and General Electric, Britain's BBC, and Japan's Sony became worldwide creators and distributors of a wide spectrum of media products from daily news to computerized games, receivable from Siberia to South Africa.
As a result, societies under authoritarian rule have become less able to control corporate and private information transmissions. In 1989, for example, despite strict internal controls by the People's Republic of China, students with fax machines spread instant news of slaughter in Beijing's Tiananmen Square of hundreds of citizens demanding more democratic freedoms. Nevertheless, the utility for economic growth of such new media has been so indispensable to China's commerce and industry that devices for the distribution of information like taxes have been permitted to increase almost 100 times since the Tiananmen Square Suppression.
International regulation of global communications has consisted largely of adoption of desired general principles and purely technical standards. The United Nations Declaration of Freedom of Information calls for “free flow of information within countries and across frontiers.” Attempts to achieve technical compatibility of the world's communication systems are made by the International Telecommunications Union, which meets every four or five years. Within most countries governmental communications and utilities commissions create and monitor the rules for each country's domestic broadcasting and popular media. In the United States the Constitution forbids official control over printed matter, but permits broadcast regulation.
Numerous non-governmental organizations operate on national and world scales to lobby for legislation that would promote their ends. In the United States, for example, a Center for Media Education monitors national legislation to press for what it sees as more salutary public needs in television. A Cultural Environment Movement, started in the United States, presses globally against gratuitous violence and inadequate presentation of education in commercial television. Similar citizen efforts appear periodically in other nations as well.(See also Censorship; Information Society; Media and Politics; Public Opinion.)

Information technology (IT) or information and communication technology (ICT) is a broad subject which deals with technology and other aspects of managing and processing information, especially in large organizations. Particularly, IT deals with the use of electronic computers and computer software to convert, store, protect, process, transmit, and retrieve information. Over the past 20 years, its prevalence has dramatically increased so that it is now a part of nearly every aspect of daily life.

Computer-aided design (CAD) is the use of a wide range of computer-based tools that assist engineers, architects and other design professionals in their design activities. It is the main geometry authoring tool within the Product Lifecycle Management process and involves both software and sometimes special-purpose hardware. Current packages range from 2D vector based drafting systems to 3D solid and surface modellers.
CAD is sometimes translated as "computer-assisted", "computer-aided drafting", or a similar phrase. Related acronyms are CADD, which stands for "computer-aided design and drafting", CAID for Computer-aided Industrial Design and CAAD, for "computer-aided architectural design". All these terms are essentially synonymous, but there are a few subtle differences in meaning and application.
CAD was originally the three letter acronym for "Computer Aided drafting" as in the early days CAD was really a replacement for the traditional drafting board.
But now is the term is often interchanged with "Computer Aided Design" to reflect the fact that modern CAD tools do much more than just drafting.

Conclusion
From the Paper:
"The management of information technology systems in organizations has emerged as one of the most important aspects of information technology in this digital era. Although problems with information technology systems are not a new phenomenon, their impact seems more pronounced. The organizations of today face unique challenges in the information technology systems area unlike those of the traditional project management of the past. The incessant continued drive toward eBusiness means that information technology has become ever more critical to the success of the organization as a while. As a result, information systems project managers face more pressure and visibility over failed initiatives. Organizations are typically dealing with chaotic, technology-influenced projects that generate knowledge. The quality of knowledge-generating projects is also most heavily affected by the skills and intellectual capital of the project team. "

IT Essay – Information Technology in Written Form
Information technology may be the biggest term of the current century. This is because all of our lives have drastically changed through the introduction of the computer and the internet, the primary tools in expanding IT in all other fields aside from science. Now, you can download music, chat with your fiends thousands of miles away and even look for that ancient book through web libraries. In this case, it is also a good idea to write an IT essay as one of you projects in school. If you are required to write thisessay sample topic, then let me give you some ideas what subjects to talk about.
Writing an IT essay does not merely involve topics about computers and the internet. Of course, these are the primary technologies that readily reflect IT but they are not the only topic scopes to write about. Actually, you first need to have a purpose in writing. Maybe you would like to discuss your opinion in an opinion essay. Or if you want to argue that IT is a big disaster in our society, then you may write an argumentative essay. As you can see, having a purpose or goal in writing gives you a sense of direction in composing your college essays. Here are the topic interests that you may use:
- Information technology: how it has changed our lives.
- The dangers involved in IT.
- The IT industry in the globalization arena of trade.
- What Information technology devices are popular in the market?
- IT gadgets and the children’s education

What Is SNPP Paging
SNPP is a simple way for delivering wireless messages, both one and two-way, to appropriate receiving devices such as pagers and cellular phones. In its simplest form, SNPP provides a simple way to implement a “shim” between the Internet and a TAP/IXO paging terminal. In a level 3 form, it receiving end-to-end acknowledgments and replies from a two-way messaging device such as ReFLEX units. Gateways supporting this protocol have been in use for well over a year at several commercial companies such as Nextel, American Messaging, and private businesses as well. A list of companies that currently have SNPP Gateways can be found here. In order to use SNPP you must have access to the Internet by a dial-up connection or through a LAN. See It for product information.
What Is WCTP Paging
WCTP is a simple way for delivering wireless messages, both one and two-way, to appropriate receiving devices such as pagers and cellular phones. In its simplest form, WCTP provides a simple way to implement a “shim” between the Internet and a TAP/IXO paging terminal. Gateways supporting this protocol are now emerging and several commercial companies such as Skytel and Arch Wireless have their gateways in place. More companies are expected to follow. A list of companies that currently have WCTP Gateways can be found here. In order to use WCTP you must have access to the Internet by a dial-up connection or through a LAN. WCTP uses xml over http. Air Messenger supports http and https for secure connections. See It for product information.
What Is SMTP (E-Mail) Paging
This is the ability to send pages via e-mail. This is supported by most paging carriers and is a simple form of Internet Paging. Although SNPP or WCTP is the preferred method for Internet Paging, it is not used as much and not many carriers support this protocol yet. Most of our products supports Windows Messaging and SMTP with the ability to use MX Record lookups. It is recommended that you try to use MX record lookup first by leaving the SMTP Server field empty. See It for product information.
What Is TAP Paging
TAP paging allows you to send pages to the carrier over a standard modem connection and is widely support by most carriers. This method is much slower then Internet Paging but a good method for redundance in the event your Internet connection should be unavailable for Internet Paging. See It for product information.
