In a previous question, I asked about Dragon Ball Super being released before its manga. My question here is about the life cycle of a manga becoming an anime.
From my understanding, an artist or mangaka creates their comic called manga and it gets published by a major studio if it's deemed worthy. From there if it cultivates a big enough fan-base it becomes licensed by a studio like Viz, Funimation or Bandai. And from there it becomes a game, movie, t-shirt, toy, etc.
Is that the way most anime's come into play? If not, what is the proper life cycle from drawing to manga to anime?
