When did Disney buy Tron?

Could you please clarify for me when exactly Disney acquired Tron? I'm trying to get a better understanding of the timeline and events surrounding this acquisition. Did Disney purchase Tron during a specific year, or was it a more recent transaction? Could you provide me with any additional details or context regarding this acquisition? I'm particularly interested in knowing how this move fits into Disney's overall business strategy and how it might affect the Tron community. Thank you for your help in clarifying this matter.
