Since then, Anime Boston has become one of the fastest growing anime conventions in the United States.

2011 Attendance - 31,348 Unique
Otakon is the second largest anime convention in the North America and the largest anime convention in the East Coast. The convention's name is a combination of "Otaku Convention." Many people see Otakon and Anime Expo as rival conventions, but the geographic differences between both cons means that there is little overlap in terms of demographics. The convention is the largest three day anime convention in the United States, they attempted to expand the convention to four days in 1995, but it was met with lots of resistance from within the organization. Due to the massive size of Otakon, it has a huge economic impact on the city of Baltimore.
1. Anime Expo
Venue: Los Angeles Convention Center, Los Angeles, CA
Organization: Society for the Promotion of Japanese Animation (Non-Profit)
2011 Attendance - 47,800 Unique
Anime Expo has quite a bit under its name, it is the largest anime convention in North America, it is one of the longest running anime conventions, it is one of the few four-day anime conventions. Anime Expo started in 1992 in San Jose, and in 1994 the organization made a strategic move to Southern California. The convention is known for its Japanese guests, incredible number of cosplayers, and its gigantic size. I have a very long history with Anime Expo, so the convention has a strong place in my heart.
So there you have it, here are the largest anime convention in North America. This isn't a top ten list, just a list of conventions larger than 10,000, so the list will grow larger as more cons get larger in size. Of these cons the only one I have attended with some regularity is Anime Expo, but hopefully soon I can expand to attend more of these wonderful large conventions.
