Answer
NerdCon: Stories was a now-defunct annual convention for creators of online video, books, and other forms of media. The conference was co-founded by John Green and Hank Green, two brothers who are also well-known online video creators. NerdCon: Stories was held in 2013, 2014, and 2015. The convention was discontinued after 2015, but its attendees have continued to meet in informal gatherings called NerdCon: Homecoming.
