"Next generation" A term that grew popular shortly after year 2000. With new technology being adopted and developed in the gaming/3d graphics industry (high poly to low poly baking / normal maps, parallax and general shading technology).
With the sudden leap in technology being pushed further, previous and older methods still being in use were gradually referred to as 'last gen' while everyone strived to make 'next gen-' into 'current gen-' technology.
Once things subsided, the term next gen eventually stuck to this recently developed technology, even though it was now the norm. The meaning has since become a bit unclear, and is used very liberally, even as a marketing term.
In the general publics eye, it is also often used as meaning 'better looking graphics', regardless of what technology is being employed, failing to realize the large quantity of aspects being involved, just as with the making of a movie.
Used when talking about video game systems that are coming out or have just came out. Currenlty, this gen systems are the Dreamcast, PS2, Xbox and GameCube. The next gen will be the PS3, N5 and Xbox 2.
Broadway Next Gen is a tiktok storyline that follows kids of different musical characters. No one really understands the story I wish i could tell you. I just love the videos that follow. It's fun to cry you know?
