React (media franchise)

React (sometimes stylized in all caps as REACT) is a media franchise created by the Fine Brothers consisting of several online series centering on a group of individuals reacting to viral videos, trends, video games, film trailers, or music videos. The franchise was launched with the YouTube debut of Kids React in October 2010, and then grew to encompass four more series uploaded on the Fine Brothers' primary YouTube channel, a separate YouTube channel with various reaction-related content, as well as a television series titled React to That. In 2016, the duo announced React World, a program and channel in which they would license the format of their React shows to creators, which led to widespread negative reception from viewers and fellow content creators, as well as confusion about what their format is.
