Why doesn Ghibli make TV series?
Ghibli was established specifically to make films. TV anime in Japan are made under such tight schedules and budgets, that it’s almost impossible for Miyazaki to make the high quality anime he wants to make. This is rather risky, since Ghibli can produce only one movie per year or so, and one movie flop will really damage Ghibli financially. However, the strategy has paid off so far. Ghibli has tried TV with a TV movie, “Umi ga Kikoeru”, which was made by the younger staff, but it went way over budget and schedule.
