IXL Learning was founded in 1998 when we released Quia Web, the first website that allowed teachers and learners to create and share customised study materials. The initial version featured three formats: a matching game, a concentration game and flash cards. This was soon followed by the addition of quizzes and numerous more game types. The concept was an overnight success, and Quia Web quickly became one of the most popular education sites in the early days of the internet.
