Google Trends Analysis of Moodle

Google Trends is a public web facility of Google Inc., about Google Search, that shows how often a particular search-term is entered relative to the total search-volume across various regions of the world, and in various languages. The horizontal axis of the main graph represents time (starting from some time in 2004), and the vertical is how often a term is searched for relative to the total number of searches, globally.[1] Below the main graph, popularity is broken down by region, city and language. It is possible to refine the main graph by region and time period.  In the chart below I have charted a comparison for our LMS, Moodle, our former LMS WebCT,  an open source alternative Sakai as well as market leaders Blackboard and D2L.  Note the changes in the lines in the 2006 -2007 time frame when we completed our transition from WebCT to Moodle
