by what are those legal sites their talking about ?
For legal anime streaming sites, that would be Viz Media, Aniplex of America, FUNimation, HULU, and Crunchyroll. For simulpub, it's Viz Media Shonen Alpha, Yen Press (I think), and Crunchyroll. Since you're from Saudi Arabia, I think Crunchyroll is open to your region since HULU might be restricted to the US. Auron570 told me HULU isn't accessible in Canada.
Good point, but I still believe the industry is still growing just not as rapidly like video games and comic books. When I saw San Diego Comic Con and how much coverage that they had compared to AX, it hints to me that the comic book industry was way affluent than anime industry. I haven't seen other industries besides anime and manga.
