"...a metamedium, whose content would be a wide range of already-existing and not-yet-invented media."
Old media can be inserted and reconfigured within digital space and become something else and new. For example, you can digitize a text, then cut, copy, paste, find...analyze it with a computer.
New media also consists of not yet invented media, software and hardware that reinterpret it. Examples of this might be social media, 3D scanning, MMORPG, etc.
An early example of analog meta-media is the telegraph to telephone. The map above, from 1871, shows how copper wire connected the world with the telegraph network. The telegraph was the first electronic mass communication device, but it used Morse code to send and translate messages with a complicated series of electrical dashes and dots. Just like the telegraph, the telephone uses electricity and can use the preexisting infrastructure of the telegraph, but is a completely new media. As Adele Goldberg states above, the telephone example consists of “..already-existing and not-yet-invented media.”
"new media” is “new” because new properties (i.e., new software techniques) can be easily added to it.
Primarily known for his silk screen paintings, in this video Andy Warhol uses a computer to add new techniques to his aesthetic.
In his book "The Language of New Media, Manovich draws parallels to way cinema, particularly Dziga Vertov's early avant-garde film "Man with A Movie Camera" (1929), and digital systems work.

Numerical Representation: "All new media objects, whether created from scratch on computers or converted from analog media sources, are composed of digital code; they are numerical representations."
New Media == 01001110 01100101 01110111 00100000 01001101 01100101 01100100 01101001 01100001
Modularity: "Media elements, be they images, sounds, shapes, or behaviors, are represented as collections of discrete samples (pixels, polygons, voxels, characters, scripts). These elements are assembled into larger-scale objects but continue to maintain their separate identities. The objects themselves can be combined into even larger objects—again, without losing their independence."
This image shows some of the files that make up my website, listing them in alphabetical order. My website as a single entity is created using most of these files, but they still exist individually. For example, an image that is used to create my website can still function as an image on its own.
Automation: "The numerical coding of media (principle 1) and the modular structure of media objects (principle 2) allow for the automation of many operations involved in media creation, manipulation and access."
Because this Wikipedia entry for New Media is digital and all of the words, letters and numbers exist on their own, we can use the Find tool to focus on one phrase and automate the finding of it.
Variability: "A new media object is not something fixed once and for all, but something that can exist in different, potentially infinite versions. This is another sequence of the numerical coding of media (principle 1) and the modular structure of a media object (principle 2)."
New Media can be a contentious name because it is always changing and adapting. It's a fluid development.
Using media from various resources, new media artist Cory Arcangel uses video games, TV shows, YouTube clips, default software tools, devices and sculpture to comment on the contradictions, influences and expectations of contemporary digital life.
Software and digital tools are not neutral; they are embedded with the ideologies and politics of their creator. Whether that be completely free and open sourced software (HTML), a controlled and automated space (Facebook), or controlled hardware (Apple).
