None of the AJAX components is new, or revolutionary (or at least evolutionary) as the current buzz around AJAX might suggest: all the components of AJAX have existed since sometime in 1998. The name AJAX was born in 2005 and gained much popularity when used by Google in many of its applications. What's new with AJAX is that for the first time there is enough energy in the market to encourage standardization and focus these energies on a clear direction of evolution.
