According to what McLuhan wrote in chapter one in “Understanding Media”, McLuhan pointed out that a medium is always under another medium. The example that he gave was “a contenting of writing can be a speech, a written word is the content of print and print is the content of telegraph”. It’s because there are a lot of ways to spread ideas and information under the technologies that we have. Also note that there are a lot of mediums, and ways of medium shows. This process sharpens the gaps between generations.

Ageism became a problem in our society. The media is more important than the content itself. It’s because under the medium that information locates, it can filter who can read the information. For example having printed versions of newspapers, mainly elder would buy and read through it when they are on the subway or bus. On the other hand, if the news was an online version, then more young people would get this information on their phones compared to the elderly.

Moreover, the time and the packaging of the information are the keys to spread information. For example, watching a newscast isn’t as emotional and conversational as a TV show that broadcast the same crime or event. People would likely talk about it, more people would bring up the problem. And this message would be on Twitter, Facebook, Instagram, and all kinds of social media. It’s great that we have all this information online and easily get it. Although we can get information quickly and easily we wouldn’t know or make sure that what we are looking for is the truth or the whole story. Often we lose the truth from what we are looking at online, and the phenomenon turns out what we often say today “fake news”.
