Cricket Australia has floated the idea of day-night Test cricket matches being played in Australia.
I've an open mind on the topic, but would like to see it trialled in the domestic four day comp (Pura Cup) first. In fact it was tried there a few seasons ago and didn't bring the crowds into the grounds, so I wonder whether things are likely to improve.
Throughout out the world, except for England ( where the grounds are small and admission prices high) and Australia (when it plays England), Test cricket is not a popular spectator sport. It remains an acquired taste and, as most leading players would surely admit, the highest form of the game.
It does deserve to be preserved though, and playing it at night may provide more opportunities for spectators and, depending on time zones etc, for the TV networks who provide by far the largest audience for it.
