Social media V Social networking sites

Definition to explain the difference between social media and social networking:

"We use the term “social networking” to describe sites primarily designed to facilitate interaction between users who share interests, attitudes and activities, such as Facebook and MySpace. We use “social media” to refer to sites that allow individuals to share content they have created, such as YouTube (video sharing) and Flickr (photo sharing). While interaction occurs on social media sites, the primary purpose of the site is to publish and share content."
