The work that Edutechnica has done to pull this information is great, please note that the change from 800+ FTEs to 700+ FTEs since last time the update was released could have a minor effect on the data. All caveats and considerations (and a brief interesting introduction) are available at http://edutechnica.com/2015/03/08/lms-data-spring-2015-updates/).
According to the post,
Blackboard is an interesting case study for this update given its most recent M&A activities. By considering unique ANGEL, Blackboard Learn, and Moodlerooms installations and then de-duplicating institutions, Blackboard’s overall LMS market share has dropped to 44.1% of institutions from an estimated 80-90% following the WebCT acquisition in 2006. Of the remaining ANGEL installations, fewer than one third are currently investigating Blackboard Learn (more than one third but less than half are exploring non-Blackboard solutions; the final third has until October 2016 to migrate to another LMS). The US higher education market for LMS products has clearly become very saturated.
Since September’s release of the updated information, Moodle has grown to over 20% of the higher ed market and Canvas to over 12% (though with a larger percentage of enrollments, suggesting that Moodle is dominating a market of smaller institutions).
