From the NBC Insider page: "A new season is coming back to NBC this summer. Who Do You Think You Are? will be returning to NBC on July 10th, with new episodes premiering Sundays at 7 p.m. ET. Episodes will be available to stream on Peacock the following day. The celebrities featured in this upcoming season are Allison Janney, Billy Porter, Nick Offerman, Zachary Levi, Bradley Whitford, and Zachary Quinto. " The past few seasons have been on the cable channel TLC. Nice to have it back on the broadcast channel.
