It will be wrong to say that women's events doesn't bring the revenue. The WBBL has brought in good amount of profits for Cricket Australia, and the women's Hundred has done the same for ECB. If the BCCI comes up with WIPL in the future, then I am 100% sure that they will get good profits as well. The main issue in my opinion is that the cricket boards are dominated by men in top positions. Female members are there just to make up the numbers and don't hold any real power. So they can afford to ignore women's cricket.
Can you come up with stats that how much profitable WBBL is for CA and how much ECB earned from The Hundred Women's Competition 2021? I would love to see the stats.
Woman's are doing very good when it comes to Tennis, Athletics (swimming, racing, table tennis), Basketball etc. But unfortunatly we were not able to see too much spark from woman's in cricket. Reasons may vary but in my opinion there are not much players not audience that are interested Woman's cricket.
