Test cricket was born in 1877 and for around 100 years a cricket field looked exactly the same: White clothes and a red ball. Then there was a sea change and little by little innovation flooded the field.
Coloured clothing. Day night matches. The white ball. Third umpire. Snickometer. Hawkeye. Hotspot. Fielder commentary. Spidercam. LED stumps...
Cricket looked different with each passing year. It's not just the formats getting shorter. This year spectators were perplexed to see umpire Bruce Oxenford wearing a hand shield in an IPL match.
