How the centre of gravity in cricket has shifted from the old. Anglo-Australian axis?

The centre of gravity in cricket has shifted from the old, Anglo-Australian axis
because in recent years ‘the innovations in cricket technique have mainly come from the practice of sub-continental teams in countries like India, Pakistan and Sri Lanka. Pakistan has pioneered two great advances in bowling : the ‘doosra’ and the ,reverse swing’. Both skills were developed in response to sub-continental conditions : the doosra to counter aggressive batsmen with heavy modern bats who were threatening to make finger-spin obsolete and ‘reverse swing’ to move the ball in on dusty, unresponsive wickets under clear skies. Initially, both innovations were greeted with great suspicion by countries like Britain and Australia which saw them as an underhanded, illegal bending of the laws of cricket. In time, it
came to be accepted that the laws of cricket could not continue to be framed for British or Australian conditions of play, and they became part of the technique of all bowlers, every-where in the world.
