History of Adobe Day CQ5

In this post, I would like to explain AEM history… Well, in our previous post we got idea on Content Management System and their benefits. Now let’s understand about Adobe Experience Manager (AEM).


We already know, AEM is enterprise web content management system, that is currently available from Adobe Systems. As known as AEM is an Adobe product since it was acquired Day Software.

Day_Software_LogoYes, this product was originally started by a Swiss company Day Software in early 2000 with the name “Communique”. CQ is the short form of “Communique“. Day Software was an enterprise content management software company. It creates content management infrastructure and enterprise content management applications in the Day Communiqué product. It is most important product is Day Communiqué Web content management system (WCMS).

It is used for public websites and large corporations such as McDonald’s, Avanza and Daimler.


After that Day is engaged in the content repository API for Java standardization process and contributes to open source software projects such as Apache Jackrabbit, Apache Sling and OSGi. In their earlier days, CQ5 is a version of Day CQ portfolio developed by a Day Software in 2008, followed by Day CQ 3.5, 4.0, 4.1, 4.2, 5.0, 5.2 and 5.3. In this Day CQ software it has in web based IDE called as CRX , Felix console as a web console for controlling and requiring the OSGi services, Sing web application framework which is used for content oriented applications, Java content repository which specifies a vendor-independent and implementation-independent way to access content bi-directionally on a granular level within a content repository. (These OSGi, Apache Sling, JCR is more important to know to learn AEM bascis. So just remember these terms. I will explain in more details in up coming posts. )

On October 28, 2010, Adobe systems completed its acquisition of Day Software. After that Adobe Systems renamed Day CQ5 as Adobe CQ5.
Adobe systems continued Day CQ versions following the release of the fifth version of CQ5 i.e., 5.4 and 5.5. Later, Adobe has released 5.6.1 version and it is called as Adobe Experience Manger (AEM). From this version only we calling as AEM. Adobe also introduced a new versions AEM 6.0,  AEM 6.1, AEM 6.2 and AEM 6.3. From their each any every release, they are improving the product features, UI  and functionality. This product is supporting for almost all technologies to integrate. It supports multi lingual websites and Mobile websites. We will discuss more in detail about AEM features and its complete picture in upcoming posts. Here I just want to show all  AEM products versions history. Let ‘s have a look.
