When did this interview drop? December 2017.

What else is in this interview? This is where we learn about Yamoshi, and the Namekian Book of Legends is also name-dropped.

So what about the interview where we learned about S-Cells? Well, it was another Saikyo Jump interview! No interviewer attribution. because Toriyama had designed and written that and it was the next big thing coming out. The interview where we learned that dual-eye-type scouters exist? Published in Saikyo Jump, and published a little bit ahead of Resurrection 'F' where we see Tagoma with a dual-eye-type scouter. The interview that named Goku's mother, Gine? Published in Saikyo Jump (a Shueisha magazine), just so happened to be conducted by Naho Ooishi, just so happened to come printed within the Episode of Bardock Super Kanzenban supplemental booklet (which Ooishi wrote and drew), which just so happened to be just ahead of the Jaco the Galactic Patrolman collected volume which would debut 'Dragon Ball Minus' and Gine.

What almost all these 'interviews' are, instead, are carefully-timed and carefully-crafted pieces of marketing/propaganda in service of a specific production. who's on the same bankroll as the rest of them.) (*AT BEST we actually get Naho Ooishi or some other Dragon Ball-specific person. These interviews aren't conducted by an unbiased third-party source and printed in independent publications they are conducted by nameless Shueisha employees* and published in Shueisha magazines and typically timed to new Shueisha (and by extension Toei or Bandai Namco) products of the same franchise. These interviews aren't what you think they are.

OK, so hear me out! I promise I get somewhere here! It doesn't compare to something that undertakes actual though, planning, editing, etc. I will never understand how people are so happy to treat things he makes up on the spur of the moment - often in response to leading questions where he panders and gives the answer they want to hear. Not particularly interested in the 'what counts as THE CANNONS' aspect, but:
