Cricket has never had such an enormous and variable audience and therefore, quite rightly so, a plethora of ideas and innovations are cropping up to make the game even more interesting.
The famous marketing line of a "customer is always right" is the mantra that the cricketers and the marketeers are vociferously following. The cricket fans want action, glamour, heroes and trend setters and the T20 format is ideally suited to provide that.
The changes in the rules of cricket, therefore, are being gradually tested on the shorter format of the game and in tournaments that are independently run, like the Indian Premier League (IPL). The "Impact" player option has been introduced in this years' edition of the IPL and one can already see its usefulness.
