History tells this story best: Microsoft launched Microsoft Dynamics CRM 4.0 in December 2007, and in April 2008, Microsoft Dynamics CRM Online, an on-demand service, was introduced. Just four months later, the September 2008 Update for CRM Online was released. Then, at the end of 2008, several free CRM Accelerators were launched with new functionality for Analytics, eService, Event Management, and Enterprise Search, as well as a Business Productivity pack, Extended Sales Forecasting, CRM Notifications, and Sales Methodology support.
