How can we distinguish the past and identify culture. Different versions and styles of media history do make a differnence. histoey tells us what is important and what isnot because those important stuff, even assumptions have been keeped although much tastes may have changed.

History tells us who is significant and wo is not as well as about the meanings of media, qualities of human communication, and causal mechanisms that account for historical change. The author refered the meaning of media what he thinks. media  includes varies medium which is a middle platform connecting  the entertainment outlets and audience. media can be seen a unified natural entity while medium is a bridge linking our eyes and the outside world that it helps us to experience as sights.

It pays to be careful with language, and yet media seem to be hard to talk or write about with much precision. Media can be described as “the end of that History”, with a capital H, was more clearly in sight. Media is a becoming process, never stop. it tends unthinkly to be regarded as heading a certain “coherent and directional” way along an inevitable path, a history, toward a specific and not -so-distant end. For example, blogger arise has been followed by facebook occured. We use these platforms just for sharing daily life and communicating with friends so no matter which format is. blooger, facebook, twitter, in my opinion, all of them are same in content but with different formats.

All historical subjects are certaintly not alike. The histories of science and art, for instance, differ considerably in the construction of their respective subjects. The art historical object from long ago- a vase, painting, or sculpture- is still art today, however much tasts may have changed. The theory from Galileo has been proved wrong  because his theory only can be used in a specific condition. Doubtnessly,  Galileo is a great scientist because what he did also made a  huge contribution for generations although it was wrong. But the scientific object from long ago is not science at all. what kind of historical subjects are media? Are they more like nonscientific? Science represents nature, however, media seem more involved in human culture. So media is a kind of non scientific object.

McLuhan mentioned that media is not just that each new medium represents its predecessors. media represent and delimit representing, so that new media provide new sites for the ongoing and vernacular experience of representation as such. Smartphone has camera and recorder function, even can be used as a small laptop although the quality of photo and records are not good as those professional technology, it is easy to use and bring. calling and texting are basic functions for mobile phone. the reason why manufacture make provement becuase the market need.
