Ajax is a new web approach that marries the benefits of both screen and paged-based approaches. By allowing more sophisticated functionality using easier-to-implement web standards, Ajax is proving a real alternative for creating powerful web applications. several large companies including Google have created amazing applications using the technology: Google Maps, Google Gmail, and Google Suggest are all built using Ajax. Another reason is the continuing adoption of standards compliant-browsers that support Ajax technology, most notably Firefox, Safari, Opera, and Internet Explorer 6.
