"For the past decade, the LMS market has evolved from providing tools that were purchased at the departmental level to enterprise-class systems purchased at the institutional or even system-wide level. However, since about 2004 the market has been fairly consistent, dominated by Blackboard corporate strategy.
Blackboard went public in 2004, signaling a real market worth of investors' attention. In 2005 – 2006, the market was dominated by Blackboard's acquisition of WebCT, the number 2 player in LMS, resulting in a somewhat extended Department of Justice approval cycle. Starting in 2006, Blackboard was awarded the infamous '138 patent and subsequently filed suit against Desire2Learn, the new number 2 player in LMS. About this same time, open source started to become a viable alternative to proprietary systems in general, and Blackboard in particular, in the form of Moodle and Sakai. From 2006 – 2009, open source became fully established for campus-wide or system-wide LMS deployments. In late 2009, Desire2Learn successfully fended off Blackboard patent lawsuits, ultimately resulting in all 38 claims being ruled invalid by a US Court of Appeals. On the heels of these efforts in 2009, Blackboard purchased Angel, taking another competitor out of the market."

"A few months back I submitted the smallest speck of an idea for a talk I was hoping to present at Over The Air in London. Having presented at Over The Air before I assumed my experiences this time around would more or less be the same - a chance to bounce a few of my recent thoughts off two-dozen or so UK developers.
To suggest that my assumption was wrong would in-fact be a massive understatement...
Three weeks later, the dust is still settling on the 90,000 140,000 presentation views, hundreds of tweets, and multitude of conversations, and I finally have time to provide the presentation with a much-needed introduction."
