2. Further Development of Mass Media

3. Chinese Mass Media

4. Newspapers in Ancient Cultures

5. Spreading Information about the World

A. The history of mass media can be traced back to the days when dramas were performed in various ancient cultures. This was the first time when a form of media was "broadcast to a wider audience. The first dated printed book known was printed in China in AD 868, although it is clear that books were printed) earlier. Movable clay type was invented in 1041 in China. However, because of the slow spread of literacy to the masses in China. and the relatively high cost of paper there, the earliest printed mass medium was probably European popular prints from about 1400. Although these were produced in huge numbers, very few of the early examples survive, and even most of those known to be printed before about 1600 have not survived.

B. The term "mass media was connected with the creation of print media. This form of media started in Europe in the Middle Ages. Johannes Gutenberg's invention of the printing press allowed the mass production of books. He printed the first book on a printing press in 1453. The Gutenberg Bible, one of the books he published, was translated into many different languages and printed throughout the continent. The invention of the printing press in the late 15th century gave rise to some of the first forms of mass communication, thanks to the publication of books and newspapers on a scale much larger than was previously possible. The invention also changed the way the world received printed materials, although books remained too expensive to be really called a mass-medium for at least a century after that.

C. Newspapers developed from about 1612, with the first example in English in 1620; but they didn't spread much until the 19th century. The first high- circulation newspapers appeared in London in the early 1800s, such as The Times, and were made possible by the invention of high-speed printing presses and railroads which allowed distribution over wide geographical areas.

D. The phrase "the media" began to be used in the 1920s. The notion of "mass media" was generally restricted to print media up until the post-Second World War, when radio, television and video were introduced. The audio-visual facilities became very popular, because they provided both information and entertainment. because the colour and sound engaged the viewers/listeners and because it was easier for the general public to passively watch TV or listen to the radio than to actively read. In recent times, the Internet has become the latest and most popular mass medium. Information has become readily available through websites and cosily accessible through search facilities. One can do many activities at the same time, such as playing games, listening to music, and social networking
