VidCon is a multi-genre online video tech conference, held annually in Southern California since 2010 and currently organized by ViacomCBS. Originally conceived by Hank and John Green of the Vlogbrothers YouTube channel, the convention is one of the largest of its kind, gathering thousands of online video viewers, creators, and industry representatives worldwide. In February 2018, Viacom acquired VidCon; however the conference remains a standalone subsidiary. Its offices remain in Missoula, Montana, sharing a building with Complexly.
