Welcome to the unit. Various types of mass media have developed over time. Watch the video and finish the following exercises. The term mass media was used for the first time during the one thousand nine twenties. IT refers to the sources of information and news to reach a large audience. However, the mass media existed long before the term was used, and over time, different types of media have developed. Take a walk through the city shops and you won't be able to find a view without outdoor media, which is one of the earliest forms of mass communication. Outdoor media has been around since ancient times. All shop signs, posters and advertisement outside buildings and inside shop windows are forms about door media. Another early form of mass communication is print media, which gained its foot hold and distribution to the masses with the invention of printing. Continued improvements over the centuries allowed books, magazines and newspapers to be printed in large quantities. Broadcast media has two main components, radio and television. Around the start of the twenty eighth century, people began to develop radio technology, and by the nineteen twenty thousand people tuning into radio programs for news and entertainment, the television appeared in the U. S. A. And the U. K. In the nineteen twenty. Over time, watching news on television, first in black and White and then in color, became a daily habit for many people. The digital industry began with the invention of the internet, first available for public use in the nineteen nineties. IT quickly became the center of mass media as the digital format created an innovative source for news, films and music recordings. IT has also allowed new forms of media to be introduced, such as blogs and forms where people all over the world can share information. Even outdoor media has become digitalized with billboards that can change messages every few seconds as opposed to every few weeks.
