What was the exact first release date of the Just Dance series?

The Just Dance series first released on November 17, 2009, with the original game simply titled Just Dance. Ubisoft developed and published it for the Wii, making it the franchise's first main installment.

The original game's central idea was straightforward: players held a Wii Remote and copied choreography performed by an on-screen dancer. The game grew from motion-control concepts Ubisoft had explored in a minigame for Rayman Raving Rabbids: TV Party. Although critics often objected to its basic motion detection and limited progression, its accessible party format helped it find a broad audience.

The date is sometimes confused with later entries in the series. Just Dance 2 arrived on October 12, 2010, Just Dance 3 followed on October 7, 2011, and Just Dance 4 launched on October 9, 2012. November 17, 2009 therefore identifies the franchise's first release, not a sequel or a regional launch of a later game.
