User-generated content (UGC), alternatively known as user-created content (UCC), emerged from the rise of intelligent web services which allow everyday users to create content, such as images, videos, audio, text, testimonials, and software (e.g. video game mods) and interact with other users.[1][2] Online content aggregation platforms such as social media, discussion forums and wikis by their interactive and social nature, no longer produce multimedia content but provide tools to produce, collaborate, and share a variety of content, which can affect the attitudes and behaviors of the audience in various aspects.[3] This transforms the role of consumers from passive spectators to active participants.[4][5][6]
User-generated content is used for a wide range of applications, including problem processing, news, entertainment, customer engagement, advertising, gossip, research and many more. It is an example of the democratization of content production and the flattening of traditional media hierarchies. The BBC adopted a user-generated content platform for its websites in 2005, and TIME Magazine named "You" as the Person of the Year in 2006, referring to the rise in the production of UGC on Web 2.0 platforms.[7][8]CNN also developed a similar user-generated content platform, known as iReport.[9] There are other examples of news channels implementing similar protocols, especially in the immediate aftermath of a catastrophe or terrorist attack.[10] Social media users can provide key eyewitness content and information that may otherwise have been inaccessible.
Since 2020, there are an increasing number of businesses who are utilizing User Generated Content (UGC) to promote their products and services. This approach is considered a cost effective and authentic way to enhance brand's image and boost sales. Several factors significantly influence how UGC is received, including the quality of the content, the credibility of the creator, and viewer engagement.[11][12] These elements can impact users' perceptions and trust towards the brand, as well as influence the buying intentions of potential customers. UGC has proven to be an effective method for brands to connect with consumers, drawing their attention through the sharing of experiences and information on social media platforms.[13][14] Due to new media and technology affordances, such as low cost and low barriers to entry, the Internet is an easy platform to create and dispense user-generated content,[15] allowing the dissemination of information at a rapid pace in the wake of an event.[16]
