Test cricket is only being played seriously by the top four teams. Other than that test ticket is not something that excites a lot of people or even the teams. I absolutely do not think that test cricket has any future in today’s day and age. I really think that ICC should forget about test cricket and the resources that they are spending to make test cricket better, they can spend that on T20 cricket, and by doing so a lot of other countries and teams are going to be interested in cricket. And that is something cricket badly needs right now.
The top 4 test playing nations have a good revenue generating model from.test cricket. That is one reason other cricket playing nations avoid test. Next the cricket boards of these top 4 are big revenue generator for ICC. The last one is that they have a good talent pool for test cricket and due to that they have a somewhat good fan base.
Other boards are struggling to generate revenue by themselves they are dependent on the amount they get from ICC. That is the reason those test playing teams are compelled to play test cricket. The way things are going in cricket it is just a matter of years that test cricket would fade away then ODI and only T20 format will be played.
The other cricket boards are actually not in favor of continuing test cricket in my opinion, because of bad revenue.
We all know that ICC basically is being run by the top four cricket boards.
As they are generating, go to revenue from test CRICKET, they are not going to let ICC move on from it.
