VidCon is the most important annual online video convention in the world. It has been held in places such as the United States, Australia, London, Asia, and in 2021 it is coming to Mexico for the first time to bring together the entire community of content creators, fans, brands, and executives who are passionate about online video and building diverse communities.

VidCon was founded by YouTube veterans "Vlogbrothers" John and Hank Green and was acquired by ViacomCBS in 2018.
