No.1 What is Kenjiro’s feat ?
In 1926, Kenjiro Takayanagi achieved the world’s first brilliant feat of invention of television in Hamamatsu city, Shizuoka prefecture. According to the physics teacher of our school, Kenjiro’s projecting system ーscreening a letter on a cathode-ray tube electronically instead of using a mechanical systemー has a huge impact even in modern times. The motivation of Kenjiro’s study was his pure feeling that he wanted to show everybody things far away.

No.2 How did the Mass Madia develop ?
Monochrome television became popular all over Japan when the Crown Prince of Japan got married, and color television did so through the Olympics in Tokyo in 1964. After that, satellite broadcasting and digital broadcasting started.
Along with this change, the Internet became familiar with us in a short term,which made our society more convenient. Now, we have much more tools to tell information than people of the time which Kenjiro lived expected and a lot of information is flying at incredibly high speed on the Internet.
However, are the information used correctly?

No.3 Outbreak of Fake News
In 2016, a post on social media got attention all over Japan. So many people inquired of the zoo or police for help because they saw a post telling a lion had escaped from the zoo a few days after big earthquakes had happened in Kumamoto. This was fake news, but it extremely confused people.
Nowadays, there is so many fake news on the Internet that we can’t check the truth of each piece of information.
No.4 Are Japanese People too Relying on Information ?!
On the other hand, there is a surprising result of the survey. In a part of a question, “How much can you trust newspapers and magazines?”. Japanese people believed them far more than those in any other developed country. The mass media,a kind of a corporate giant, is called “The fourth power”. Because it has a longer history than the Internet, the older the age group, the more people tend to view the information from the mass media as a truth. However there could be fake news or controlled information.
Conclusion
“Information” has always been required, and it has had great influence. Therefore, it might change not only the style of our daily lives, but also national administration and global relationships.
We’d like to deal with this quickly improving information society by refining our skills, particularly “media literacy”. In order to do so, what is necessary to us is to struggle to think by ourselves without giving up and continue to seek the truth together with friends, family and anyone in the world.
This is our conclusion of our research.
