Not talking about Hollywood or high end film sets. Or something like a Nike or Superbowl ad, which has the budget of a small movie.Those can use anything, even real life helicopters. Also not familiar what they use for sports (another special case).
But for millions doing content creation (professionally), news, ads, events, and such, I see DJI dominating. Again, I mean the non-FPV space (unfamiliar with that).
Content creators tend to use FPV more and more, because it lets them do tricks and "spectacular" shots not possible otherwise. But in many cases, even if the drone itself isn't DJI (and it usually isn't, for now), the video system is DJI (O3).
