Videogame webcaster Twitch will stage its first-ever live TV viewing event in partnership with TBS, as part of a promotion for the upcoming season of the cabler’s geek-competition series “King of the Nerds.”

The event, to be held at Twitch’s San Francisco headquarters on Friday, Jan. 16, will feature a preview screening of the first 30 minutes of the first episode of “King of the Nerds” season three, slated to debut the following week. Popular Twitch gamecasters Marcus “djWHEAT” Graham and Jon Carnage are set to moderate the event, to be streamed live on twitch.tv/twitch on Jan. 16 at 6 p.m. PT.

In addition, “King of the Nerds” hosts and executive producers Robert Carradine and Curtis Armstrong (pictured, above) will be on hand and will engage in a chat session live on Twitch.

Amazon acquired Twitch last summer for around $1 billion, as the e-commerce giant expands its online-video business; Twitch had also been in talks with YouTube. Twitch claims to have more than 60 million monthly users, who watch and chat about live gameplay produced by more than 1.5 million individual broadcasters.

Twitch has in the past live-streamed non-gaming events, such as concerts, but this is its first partnership to broadcast a traditional TV show.

In TBS’s “King of the Nerds,” 12 competitors vie for the ultimate nerd title and the $100,000 grand prize in a series of challenges. Season three is set to launch on Friday, Jan. 23, at 9 p.m. ET/PT on TBS. Guest appearances in season three are scheduled to include Danica McKellar, Michael McMillian, Yaya Han, Billy Boyd, Moby, Lisa Loeb, Travie McCoy, Penn Jillette and Rachelle Lefevre.

“King of the Nerds” is executive produced by Ben Silverman, Chris Grant and Corie Henson of Electus and Craig Armstrong, Rick Ringbakk, Charles Wachter and Anthony Carbone of 5X5 Media, as well as Carradine and Armstrong (who starred in 1984 classic “Revenge of the Nerds” and its sequels). Electus International, the global distribution arm of Electus, distributes “King of the Nerds” internationally.
