Social media: Participatory online media where news, photos, videos, and podcasts are made public via social media websites through submission. Normally accompanied with a voting process to make media items become "popular".

A social network is a social structure made of nodes (which are generally individuals or organizations) that are tied by one or more specific types of interdependency, such as values, visions, idea, financial exchange, friends, kinship, dislike, conflict, trade, web links, sexual relations, disease transmission (epidemiology), or airline routes.
