In Avengers: Infinity War, when Thanos snaps his fingers with the Infinity Stones, half the population vanishes.
In Avengers: Endgame, Banner snaps his fingers with the Infinity Stones & the vanished people are brought back. Later on, when Tony snaps his fingers, Thanos & his army vanishes.
In Spider-Man: Far From Home, the news & people refer to the Snap as the Blip.
Why did the MCU decide to officially call this event as the Blip?
I might be imagining but I think the Avengers referred to it as the Snap.
