The term new media refers to various technologies that have emerged or seen rapid growth on a global scale during the latter part of the 20th century and into the new millennium. Most people who have an Internet connection are already aware of some of the major types of this media, which includes social networking sites such as Facebook and Twitter, as well as blogs and video sharing sites such as YouTube. This type of media has also greatly advanced cellular communications in the last twenty years, through applications that connect with the Internet and other technologies. As new media is constantly evolving to connect to as many different platforms and people as possible, one of its most defining characteristics is interactivity.
