There was a time when HQ Trivia was on everyone's lips, and millions of people were playing it in hopes of winning some money from its prize pot. Then the trivia show app was beset by one problem after another until it fell off the radar, lost its audience and shut down. CNN announced last year that it ordered a documentary that'll tell the game show's story, with the promise of launching it in 2023. Now CNN Films, the news channel's motion picture division, has released a trailer for the documentary entitled Glitch: The Rise & Fall of HQ Trivia, which is scheduled to premiere on CNN on March 5th at 9PM ET/PT.
