Today Blackboard announced that it has acquired ANGEL Learning, Inc., producer of one of the most widely used course management system (CMS) in US higher education (according to ITC‘s March 2009 Distance Education survey, ANGEL was 2nd only to Blackboard+WebCT). In 2005 Blackboard acquired its primary rival WebCT, making it quite possibly the number one CMS provider to higher education institutions in the USA..

This most recent acquisition is a surprising but not unpredictable indicator of Blackboard’s lust to dominate the higher ed CMS market. In 2006 the US Patent Office awarded Blackboard a broad and hotly contested patent on learning management system features, which Blackboard immediately used to sue its next largest commercial rival, Desire2Learn. And though Blackboard was successful in its legal actions, twice since then the US Patent Office has rejected the original 44 patent claims, first in March of 2008 and again in April of this year.
Blackboard, however, presses on, appealing the rejections, fighting with Desire2Learn in the courts, suing the US Patent Office, and even filing more patents (including one detailing a 3D learning environment, and a set of claims in Canada[!]) on which they can base new lawsuits against D2L.
As ITC noted in its March 2009 survey, ANGEL had gained considerable market share in the US, putting it in the #2 slot against Blackboard+WebCT. What once looked like good news for Angel has become a nightmare for an CMS consumer market in need of diverse and innovative choices, and a looming shadow for other CMS producers, as Blackboard continues to thwart and denigrate healthy competition in the field of e-learning. At this point I’m continuing to put my faith in Moodle, the popular open source CMS, and wondering if US antitrust law contradicts Blackboard’s aggressive behavior.
