There were also record crowds at several games a few months back all as part of a concerted effort and specially selected fixtures, The next set of games the crowds were back at a couple of thousand at most. It still has a long way to go and there is no doubt the BBC are pushing it for political reasons and because they have so little other sport, but it still doesn’t make it value for license payers money. They’d likely get more viewers for televised dominos.
I’ve actually watched a fair bit of women’s cricket (mainly on Sky) and find that a better watch.
