(keitai-l) Ten most successful content providers?

Does anyone have an idea about which the ten most "successful" content
providers (mobile) in Japan are?

Successful is an odd word to use, but I think that ranking content providers
after the number of subscribers is a good way. Revenue figures tend to
include "unwanted elements" (hand set, distribution, consulting) that is a
bit missleading, in this case. 

Cybird, Bandai, Index, MTI and Giga; are names that seem to fit into the
list. But who are the rest? ("... and where do they hide?") 




Best regards,

different companies within the industry, but none has (could?) answered this
question."
