VidCon is an annual convention for influencers, fans, executives, and online brands. The event primarily features prominent video stars from across the internet. It was founded by veteran YouTube creators John and Hank Green (Vlogbrothers), and was later acquired by Viacom in 2018 and later acquired by Informa in 2024. Its offices remain in Missoula, Montana, sharing a building with Complexly. VidCon's international presence continues to expand with additional events planned in Singapore, Abu Dhabi, Mexico City, Australia, and São Paulo. In October 2020, VidCon Now relaunched as an ongoing, free digital offering.
