While originally created as a traditional sci-fi/fantasy "litcon" embracing art, TV/film, costuming, gaming, folksinging, comics and real-space advocacy, Soonercon now crosses over to even more aspects of fandom including anime, miniature modeling, and film production.
During those years, many headliner artist and writer guests of honor, from Tim Powers and Gene Wolfe to Brad W. Foster and Robin Bailey, were welcomed to Oklahoma City.
SoonerCon 2008 was held June 6–8 with a theme of "Pieces of '08," with honored guests including toastmaster Selina Rosen, author John Ringo, and artist Tom Kidd.
Pending updates to dates, themes and guests, Soonercon continued annually in its June slot at the Reed Center and Sheraton in Midwest City through 2018, when it was realized the large but limited parking lot was actually causing a ceiling on attendees.
Growth immediately resumed the next year with a move to the larger Embassy Suites Hotel and Conference Center in Norman on June 7-9 with actor Nana Visitor of Star Trek: DS9 among the guests.
The current string was interrupted by two years postponed during the general COVID-19 pandemic shutdowns, but Soonercon 30 resumed at the Norman Embassy Suites over June 24-26, 2022.
