The HISTORY Channel's German service, run by Hearst Networks Germany, premieres "History oder Mystery?", four episodes of eight to ten minutes in which host Matthias Henke reports from the original locations in Stralsund, Kampehl in Brandenburg and Berlin while AI-generated scenes depict the events in question, from sky phenomena reported by fishermen in Stralsund in 1665 to Berlin's Teufelsberg and East Germany's ghost stations. Berlin agency HAPPYGANG produces and Jonathan Ziegler directs. Episodes go up on YouTube on Fridays at 4pm from 23 October before a linear premiere on 28 January 2027; Hearst Networks Germany managing director Kathrin Palesch calls it a new "midform" format.
