Yes to all of the above, many Sports have lost characters and have adapted accordingly, Speedway obviously suffers because it’s expensive to get in to, it’s reliant on the weather and the model of the Sport imo no longer works, especially for a modern audience, new sports have sprung up since the time we were kids, see examples in the Winter Olympics for an obvious example and the emergence of Women’s sports. Many of these newer sports are niche/minority but they are slick and professionally presented, yet look at the enthusiastic crowds.
We have had GP’s in ready made stadia, that were established and served up dross, the Cardiff GP (I forget the year, but myself and a mate went) it was appalling, and still people defended it. We can’t keep looking back, if you can’t market a team sport, that is fast, dangerous and colourful and in which a race lasts 60 secs, which is about the average concentration level of a modern day person (tongue firmly in cheek) and you have multiple Social Media platforms to do this (Insta, X, BlueSky, YT, Reddit, Mastadon, FB etc) oh and David Howe’s daughter then what hope has the sport got?!
