A significant part of Jeff Scott's "Hitchhikers Guide to the SGP" is all about the impact that BSI has had on the sport during their tenure, from the highest level(s), right down to the personal. It's quite nuanced, goes into plenty of detail, and leaves the reader in no doubts about where the blame for the current state of speedway might lie. It also touches on the impact all of this has had on the domestic UK scene.
And, certainly, the same agreement above, was the basis for the initial BSI tenure - new markets, global reach etc. etc. etc. so nothing really new there.
It is really hard to imagine exactly where / how Eurosport can make a difference. The SGP universe exists in a kind of 'bubble' on it's own, so I can quite easily see it continuing as is, and maybe consolidation is the best we can hope for.
Of course, the post-Covid-19 world will have an impact, as it will for many sports. As an example, an almost sacrosanct view was that football without fans is _nothing_, and that has been turned on it's head.
