You’ve been to the event several times already. What do you need a 60-second ad for? To convince you to go again?
I feel like Universal did what they could do — they put out spots (I’ve seen on YouTube, etc.), billboards, and so on; that feeds people going, “What is that?” and following up by Googling it, whether they find articles about it or find videos by influencers or whatever, and then be convinced to go or not.
Advertisement doesn’t work the same way it did five, ten years ago; a 60-second ad isn’t going to do anything when the only people willing to even watch an ad that long nowadays are people like you who are already know about/are going to the event anyway.
