It is sometimes useful to know the history behind something. Ankur Ahlawat, of the AEM CQ5 Tutorials blog, put together a simple list of the product history of Adobe Experience Manager (formerly CQ and Adobe CQ). In his list, he outlines when and where it started and some of the major feature points of each version of the product. I hope that Ankur continues to keep this product list up-to-date with each release of the Adobe Marketing Cloud Solution AEM—as it will be useful to look back on it from time to time.
