The Marvel Cinematic Universe name for Thanos’ use of the Infinity Gauntlet to kill half the life in the universe has seemingly undergone an evolution since it took place in 2018’s Avengers: Infinity War, with its latest moniker – ‘the Blip’ – coming up several times in the now-in-theaters Spider-Man: Far From Home.
But it’s also been called ‘the Snap’ and ‘the Decimation’ – and it seems there’s even the possibility these names refer to different aspects of Thanos’ actions. So how does it all shake out?
Well, Marvel Studios President Kevin Feige offered some clarification following the release of Far From Home, explaining the difference – in Marvel Studios’ eyes, at least – between ‘the Snap’ and ‘the Blip’.
And oddly enough, even though we’ve all just heard it for the first time in Far From Home, Feige says ‘the Blip’ came first.
“It came pretty fast. We always referred to it as ‘the Blip,’ and then the public started referring to it as ‘the Snap’,” Feige told Fandango. “We think it's funny when high school kids just call this horrific, universe-changing event ‘the Blip’.”
“We've narrowed it down to, ‘the Snap’ is when everybody disappeared at the end of Infinity War. ‘The Blip’ is when everybody returned at the end of Endgame,” Feige concluded. “And that is how we have narrowed in on the definitions.”
It’s actually unclear where the terminology ‘the Snap’ first became prevalent – it was widely used following the release of Avengers: Infinity War, and no MCU material existed to ‘officially’ name the event. At least until December, 2018 (seven months after Infinity War’s release) when a book titled The Cosmic Quest Vol. 2: Aftermath seemed to name it ‘the Decimation.’
The Cosmic Quest Vol. 2: Aftermath is a prose-style sourcebook written from the point-of-view of Dr. Erik Selvig, and uses the term ‘the Decimation’ to refer to Thanos’ actions. But the term doesn’t seem to have appeared elsewhere, and the book does not appear to be considered canon – meaning that’s likely a device of the book's author, rather than an MCU term.
So that seems to be case closed – from Marvel Studios’ own mouth, ‘the Snap’ is when half the universe disappeared, and ‘the Blip’ refers to their return. And ‘the Decimation’ is, well, nothing really.
