Milestone for an once obscure term that some 10-15 years ago, was mainly known only to virtual world users: Avatars. Jumanji: Welcome to the Jungle is this year's high profile, big budget Christmas movie, and it's about high schoolers being transported into a game world where their avatars are quite different from who they are IRL. At one point in the trailer, Dwayne Johnson casually says "avatars", as if the audience already knows WTF that even means: "I think we've become the avatars we chose!" And this is not a sci-fi movie like Tron: Legacy where the avatar aspect is more specific to the story's background, or even the actual Avatar movie, where much of the movie was devoted to explaining step-by-step what avatars are supposed to be:
6-7 years after those movies, it's enough for The Rock to say "We're avatars!" and that's all the explanation it's assumed a mass market audience needs. Then again, this is really more a matter of Hollywood executives finally understanding what their kids have been doing in Minecraft and beyond for years.
