User-generated content in the context of "News aggregator"

Social media are new media technologies that facilitate the creation, sharing and aggregation of content (such as ideas, interests, and other forms of expression) amongst virtual communities and networks. Common features include:

• Online platforms enable users to create and share content and participate in social networking.
• User-generated content—such as text posts or comments, digital photos or videos, and data generated through online interactions.
• Service-specific profiles that are designed and maintained by the social media organization.
• Social media helps the development of online social networks by connecting a user's profile with those of other individuals or groups.

The term social in regard to media suggests platforms enable communal activity. Social media helps people connect and build networks. Users access social media through web-based or mobile applications. These interactive platforms allow individuals, communities, businesses, and organizations to share, co-create, discuss, participate in, and modify user-generated or self-curated content. Social media is used to share memories, form friendships, and learn. They may be used to promote people, companies, products, and ideas. Social media can be used to consume, publish, or share news.

A creepypasta is a horror-related legend which has been shared around the Internet. The term creepypasta has since become a catch-all term for any horror content posted onto the Internet. These entries are often brief, user-generated, paranormal stories that are intended to frighten readers. The subjects of creepypasta vary widely and can include topics such as ghosts, cryptids, murder, suicide, zombies, aliens, rituals to summon supernatural entities, haunted television shows, and video games. Creepypastas range in length from a single paragraph to extended multi-part series that can span multiple media types, some lasting for years.

In the mainstream media, creepypastas relating to the fictitious Slender Man character came to public attention after the 2014 "Slender Man stabbing", in which a 12-year-old girl was stabbed by two of her friends; the perpetrators claimed they "wanted to prove the Slender Man skeptics wrong". After the murder attempt, some creepypasta website administrators made statements reminding readers of the "line between fiction and reality". This case is part of a pattern of people, especially children, developing misconceptions around the reality of creepypastas.

Web 2.0 (also known as participative (or participatory) web and social web) refers to websites that emphasize user-generated content, ease of use, participatory culture, and interoperability (i.e., compatibility with other products, systems, and devices) for end users.

The term was coined by Darcy DiNucci in 1999 and later popularized by Tim O'Reilly and Dale Dougherty at the first Web 2.0 Conference in 2004. Although the term mimics the numbering of software versions, it does not denote a formal change in the nature of the World Wide Web; the term merely describes a general change that occurred during this period as interactive websites proliferated and came to overshadow the older, more static websites of the original Web.

A fan game is a video game that is created by fans of a certain topic or IP. They are usually based on one, or in some cases several, video game entries or franchises. Many fan games attempt to clone or remake the original game's design, gameplay, and characters, but it is equally common for fans to develop a unique game using another as a template. Though the quality of fan games has always varied, recent advances in computer technology and in available tools, e.g. through open source software, have made creating high-quality games easier. Fan games can be seen as user-generated content, as part of the retrogaming phenomena, and as expression of the remix culture.
