The Day-Night Test
Traditionally, the cricket ball was red, allowing batsmen and fielders to see the ball. When the World Series Cricket started, the introduction of day-night cricket led to the use of a white ball and black sightscreen.
As pressure on Test cricket increased due to the popularity of T20,and decreasing popularity of the game ICC had been moving towards the idea of a trial day-night Test match.
To this end, versions of pink balls had been trialled as far back as 2008, in a Queensland Women v Western Australia Women match in Brisbane.
In 2010, the trials stepped up a notch, with pink balls used for the first time in day-nighters in Caribbean first-class cricket, the IPL (in nets) and Abu Dhabi.
As Kookaburra continued to tinker with the pink ball prototype, it was trialled in day-night Sheffield Shield matches.
Now, seven years after its debut, the pink ball is about to be used for the first time in a day-night Test match between Australia and New Zealand at Adelaide Oval. Now many teams ready to embrace the day-night Test in 2016. India will host New Zealand later this year.
