Question: When did the movie "The Terminator" debut?
About the article "The Terminator", section "Release".

Candidate passages:
In the "Terminator" film series, a terminator is an autonomous robot, typically humanoid, originally conceived as a virtually indestructible soldier, infiltrator and assassin.
James Cameron introduced the first terminator character in the 1984 movie "The Terminator", featuring a single cyborg simply called "The Terminator", portrayed by Arnold Schwarzenegger.
When later "Terminator" movies introduced additional models, some sources retroactively gave Schwarzenegger's character a model number, leading to multiple conflicting names. 
Comic strip stories that were printed in Terminator Salvation Comic were:  Issues 1-4: Sand In The Gears (Terminator Salvation Movie Prequel, re-printed in four parts).  
In the "Terminator" universe, a terminator is a formidable "cybernetic organism", robotic assassin and soldier, designed by the military supercomputer Skynet for infiltration and combat duty, towards the ultimate goal of exterminating the human resistance.
Terminators are indistinguishable from humans, can speak naturally, copy the voices of others, read human handwriting, and even sweat, smell, and bleed.
One of the few giveaway signs is that a dog will bark continually at a terminator.
The human resistance uses dogs to help spot them.
A trait persistent throughout the series is the faint red glow of the "robotic eyes" when online, which dim to nothing when a terminator shuts down.
In all four movies, the lack of the glow has been used to show when one is out of action.
The trait is so characteristic that light-up eyes are often found on "Terminator" merchandise, with some even replicating the dimming/reillumination effect that occurs during shut down or start up.
Guardian terminator Cameron states to John Connor in "" episode "The Mousetrap", that terminators' densities deny them the ability to swim.
T-888 Cromartie demonstrated in the same episode, however, that they can survive submerged and walk along the bed to the shore.
The prototype terminator Marcus Wright in "Terminator Salvation" did demonstrate the ability to swim, though he is the only one of his type.

In the first movie, Skynet is described as being a revolutionary artificial intelligence system built by Cyberdyne Systems for SAC-NORAD.
According to Kyle Reese, Skynet "saw all humans as a threat; not just the ones on the other side," and "decided our fate in a microsecond: extermination."
Skynet began a nuclear war which destroyed most of the human population, and initiated a program of genocide against the survivors.
Under John Connor, the human resistance turned the tide on the machines and eventually destroyed Skynet's defense grid.
In a last-ditch effort, Skynet sent a cyborg, called a "Terminator", back in time to 1984 to kill Connor's mother Sarah before she would give birth to John.
Connor sent back his own operative, a young man named Kyle Reese, to save Sarah.
The Terminator did not succeed in killing Sarah; Reese impregnated Sarah, becoming John's father, and the Terminator was destroyed in a hydraulic press.
