New Media can be dated back to (at least) when the first permanent photograph was made – the heliograph by Niépce. Nowadays, such an old process is no longer considered as “new”. That is because just for photography, many new processes were made, such as the Daguerreotype by Daguerre and many, many more generations before the modern day process.
As the sources have noted, new media usually indicates that it is an art form using technology to give it an essence, a base. In other words, new media is something people do or make using technologies. And of course it includes the developing technologies which are to come in the near, or even, distant future. Just as how a camera from back then was valued and labelled as new. These technologies brought about the change of views for photography and people began to view it as a tool to create art.
Presently, computers and its vast abilities and functions are highly linked to new media. Photoshop, flash, overture, vocaloid (voice synthesizer) are a few examples of computer software which can produce something the creator wanted to express without the use of old school tools such as paint, pencil and paper.
In my opinion, new media is an ever-changing process which is still evolving even to this very day and it will continue as long as people wish to create art in this particular form.
