Following an article I read recently, it would be interesting to note what you all think has been the most significant innovation to the game of cricket. Now this could be a particular skill, such as reverse swing, the doora, the Dil-scoop etc.

Alternatively it could be a piece of technology. The various components of the DRS such as Hawkeye and Hotspot have made a huge difference to cricket (as well as other sports).

Or perhaps it's a particular rule change? Was the change in the law following the bodyline series the most significant innovation the game has seen?

What about T20 cricket and the IPL? Players priorities have perhaps somewhat changed due to the lucrative nature of the shortest form of the game, and cricketers salaries have changed beyond recognition. Or was Kerry Packer the original significant innovator in cricket?

Discuss!
