The story
ANGEL Learning and the ANGEL LMS evolved from research at Indiana University-Purdue University Indianapolis (IUPUI). The initial research system deployed in 1996 became Indiana University's OnCourse founded by Ali Jafari and David Mills. The ANGEL LMS was created using the early system concepts and was released by the newly formed CyberLearning Labs, Inc. in July 2000. The company later changed its name to ANGEL Learning. On May 6, 2009, competitor Blackboard Inc announced that it was purchasing ANGEL Learning with the merger's completion planned for the end of May, 2009.
