According to Mainichi Online, the number of visitors to Tokyo International Anime Fair 2009 were 130,000, which was the largest since its start in 2002. The event itself was successful, but the anime producers share a sense of crisis. The main concern is that the sales of anime DVD have reached the ceiling.

Here is the graph of the anime DVD sales in Japan between 1997 to 2008.

The number in 2008 is the sum of DVD and BD sales.

The gap between the sales of successful and failed titles are increasingly large. In 2008, the sales of some successful titles were more than 100,000 copies per volume but the failed titles were sold only a few thousands or less. The anime producers regretted that they had been blinded by the competition and had released excessive number of titles. The number of titles to be aired this spring will be decreased by 30% compared to the last year.
