Wave 1 from 2005-2009 saw the inception of online communities as economic, technological and social factors enabled their emergence. Wave 2 from 2009-2016 was a period of growth where communities realized significant cost and time savings through bulk buying, lower recruitment costs and letting agencies handle more work. This improved quality through strategic and tactical approaches as well as longitudinal learning. Wave 3 from 2019 onwards involves communities evolving to focus on agility, immersion, and building insight ecosystems through asking, listening, observing and having conversational and observational insights at scale.
