The original Terminator movie directed by James Cameron was released, spawning the franchise that eventually led to Terminator Genisys.
Paramount Pictures began developing Terminator Genisys as the fifth installment in the Terminator franchise.
Terminator Genisys was released worldwide, continuing the legacy of the Terminator series.
The artificial intelligence system Skynet becomes self-aware and launches nuclear attacks, initiating Judgment Day.
Survivors of the nuclear attacks form a resistance group led by John Connor to fight Skynet.
Skynet sends a T-800 Terminator back to 1984 to kill Sarah Connor to prevent John's birth.
John Connor sends Kyle Reese back to protect Sarah Connor from the Terminator.
Kyle arrives in 1984 to find Sarah Connor already protected by a reprogrammed T-800, resulting in an alternate timeline deviation.
After being saved as a child, Sarah is raised and trained by the reprogrammed T-800, known as 'Pops'.
Sarah and Pops discover Genisys, a global operating system built by Cyberdyne that will eventually become Skynet.
Kyle Reese arrives in the altered 2017 timeline to protect Sarah Connor and prevent Skynet's creation.
Sarah, Kyle, and Pops fight a T-3000 Terminator to stop the activation of Skynet as Genisys.
Through their efforts, the activation of Skynet via Genisys is delayed, changing the future course of events.
