The fact that anime has genres, means that anime isn't a genre. Simple.I'm providing reasons for why JRPGs aren't as popular as other genres because apparently they had to be saved and were saved or whatever. There's quite a few genre conventions that quite a lot of people don't like including random battles and grinding. Aiddon said the genre is about storytelling yet those 2 things literally keep you from the story. If the game isn't entertaining to play, why should anyone play it when you can just watch the story on Youtube? Gameplay has to grow and evolve as doing the same thing over and over again always has diminishing returns. This video perfectly encapsulates why the Divinity series has done so much better than the Pillars series; Pillars only tried to recreate Baldur's Gate while Divinity improved upon it. The JRPG genre intentionally stays the same a lot of the time.
Anime is not a medium (just look up the definition of anime or medium). Anime has all the genres of anything else. Ghost in the Shell is sci-fi for example. Excel Saga is a parody. We have several other things that go straight to DVD/Blu-ray from DC animated movies to Stephen Seagal movies. We have shows that release on a website like Dr. Horrible or Reb vs Blue. There's plenty of comics that aren't superhero comics. I could probably say the typical Japanese comic is shonen (I could be wrong but it seems pretty damn popular). How is shonen literally only a genre that anime does? How is Kamen Rider or Power Rangers not a shonen? How is Teen Titans or Ninja Turtles not a shonen?
A movie that goes straight to dvd is a movie, an episodic series that goes on dvd, however, is not a tv show. It's a dvd series.
Kamen Rider and Sentai are their own unique genre called "tokusatsu", it's not even animated so it has nothing to do with anime. Not shonen. Ninja Turtles is a kodomo show, not sure what teen titans (the original, the new thing is definitely kodomo) would fit in, could go either way.
Only in the west does it seem that the typical manga is shonen. There's thousands of different manga out there, not just the 5 or so popular ones lol.
In the west it's just easier to market shonen shows cause you have a basis to go off of so they can say "you like dragonball, well, you'll like naruto!" or "you like rurouni kenshin, well, you'll like kimetsu no yaiba!" and go from there.
If I had to pick one genre that's the most popular, it'd be slice of life, since those shows you can do with a low budget and they can go in a ton of different directions so it's an easy enough thing to do.
