The document summarizes the history of learning management systems (LMS) in three acts based on a three-act story structure. Act 1 describes the early days of individual LMS vendors. Act 2 covers the period of rapid adoption and growth of many LMS vendors during the "gold rush". Standards organizations like IMS began working on interoperability standards to connect different systems. Act 3 suggests the LMS market is shifting towards a more open, interoperable "post-LMS" ecosystem driven by external tools and empowering teachers through standards.
