Many IT people watch an anime. Majority people have seen it at least once. How is it created?
It begins with an idea. Sometimes, a brainstorm is done in order to choose just one, but better idea. Occasionally, the management makes a decision. Anyway, this is the first and most tedious step. After the idea has been selected, a team is put together, which will deal with its implementation, as well sponsors are needed. Anime is actually a pretty expensive thing, because the showing cost of 52 episodes late at night is close to 50 million yen (it is about 500 000 US dollars) for 5-7 TV channels, and the anime Fullmetal Alchemist to show at 6 pm will cost in 10 times more expensive!
The next couple steps are not necessary in the case if the anime will be drawn as the manga-based. A large majority of theses Japanese cartoons are on the market. By the way, if manga was successful or not, we can find out in advance whether anime will be successful. It is worth noting that sometimes it could be vice versa - manga is drawn by anime. For example, thus it was with FLCL.
