Mukbang is an entertainment format that became popular in 2010 in South Korea: it's a livestream of a person eating food, and interacting with their audience. The word is a portmanteau of mukneun ("eating") and bangsong ("broadcast"). The researcher Kim-Hae Jin suspects that this format satisfies "the vicarious pleasures of watching someone else cook and eat", combined with entertainment and chatting.

The streaming platform Twitch added a "Social Eating" category to its site in 2016.
