Traditional Media

Before the invention of newspapers, the main source of news was word of mouth. Any writings and drawings were done by hand. Although printing presses had existed in eastern Asia, it was Gutenberg’s invention in Europe in 1453 that made printing faster and books more accessible. It reduced the cost and size of printed books and made them the first form of mass media affordable to less wealthy people. Gutenberg’s invention also quickened the spread of discoveries and information, and promoted literacy in Europe.

The printing press led to the rise of printed newspapers that appeared regularly. The first newspapers developed from around 1612 and in a short period of time, they became very popular in Europe and the European colonies. In the 19th century, they also appeared in Asia.

Newspapers and magazines are still very popular today. Although most of them have online versions, many people continue to read print media, which is considered more credible than digital media.

In the 1920s, when radio, television, and video were introduced, the phrase “the media” began to be used. Black and white television quickly became popular in the 1950s, and in the 1960s colour broadcasts started in many countries. Thanks to its audiovisual presentation, television became one of the most important forms of mass media in the 20th century. As a source of news, entertainment, and education, it still attracts a large number of viewers today.

Đọc đoạn thơ sau và trả lời câu hỏi:

Mẹ vá nỗi buồn thành manh áo niềm vui

khoác lên người con đêm lạnh giá

dọn dẹp lối đi sình lầy rơm rạ

để gót chân son không lấm bẩn bụi bùn

Mẹ khom lưng mòn mỏi trên đồng

cho dáng hình con vươn cao đứng thẳng

đêm thức trắng đêm

ngày đội mưa cõng nắng

con trẻ an lành bên giấc ngủ no say

Đường con đi rộng thênh thang tương lai

đường của mẹ gập ghềnh bao khó nhọc

con mải miết kiếm tìm hạnh phúc

đâu hay rằng hạnh phúc ở sau lưng

Parents of a Tokyo elementary school are up in arms at being asked to pay 730 dollars for their child's school uniform. A public elementary school in Tokyo's upmarket Ginza district has decided to adopt new school uniforms designed by the luxury Italian designer Armani. The bespoke uniforms, which include a hat and bag, are priced at over 80,000 (730 dollars) each. Parents are angry at the school's decision and are protesting at what they view as the exorbitant price for a uniform of an eight-year-old chilThe school said it wanted a designer uniform that represented the rich area of GinzSchool officials visited top department stores and decided to ask the fashion brand Armani to design the uniform.

The expensive uniform has created such a fuss that it has been discussed in Japan's parliament. One lawmaker said that since the school is public and not private, "a certain price range needs to be considered". Finance Minister Taro Aso sai"Clearly it's expensive. It would be tough if a student could not afford to pay for it." Japan's education minister said steps would be taken to ensure the financial burden placed on parents for uniforms, "would not be excessive". Twitter users said young children are not interested in designer clothes. The school principal sai"With humility, I take the criticism that the explanation has been insufficient and not well-timeI will go on explaining carefully to those concerned."
