Somehow I stumbled on to this diagram or "mind map" of the elearning vendor landscape at European analyst Elearnity Research.
Elearnity Research - Vendor Navigator
A combination of that chart and the Clark Aldrich Chart of Consolidations might make for quite an interesting discussion of the future of elearning. Or at least make someone look like a genius for talking through both of these in their next presentation.
Are there other charts us genius-wannabe's should be looking at? Let me know.
