over the course of one or two days, and had included ancillary events. In 2005, the 10th edition of Animethon was renamed Otakuthon. In 2006, Otaku Anime joined with other local anime clubs and individuals to turn the annual anime marathon into a full blown convention. While convention membership at the 2006 edition was free, admission fees were introduced from 2007 and onwards. There was a pre-registration option for the paid memberships, and attendees who pre-registered could arrive on Friday afternoon to receive their membership badges in order to gain instant access to all convention events on the same day at opening time. Admissions for the Masquerade and J-pop concert were included in the membership fee. The 2007 edition's outstanding success prompted Otakuthon to move its venue from Concordia University to the much larger Palais des congrès de Montréal convention center in summer 2008. This allowed the convention to increase its capacity, concentrate the main attractions on a single floor instead of multiple floors at the university, as well as free itself from restrictions imposed upon by the institution. In the same year, Otaku Anime and the other anime clubs managing the convention formed the Quebec Anime Committee, Otakuthon's parent organization. With a great number of out-of-province Guests invited in 2009, Otakuthon was upgraded from a regional-level convention to a national-level one. 2010 introduced a Thursday evening badge pickup option for pre-registered attendees, which alleviated the long lineups on Friday as well as provided them immediate access to the convention area when the doors opened on Friday afternoon. Year after year, Otakuthon has occupied more and more conference spaces and hallways of the convention center following an annual progressive growth; while in 2008 less than half of the 5th and 7th floors were booked, in 2010 nearly 80% of those floors plus the main exhibition hall of the 2nd floor (for Registration) were open for the convention. In 2017, Registration was moved to Level 1 to make space for expansion of the Exhibition Hall on the 2nd floor. Expansion of exhibit and conference space is expected to continue in the upcoming years as the convention continues to maintain a strong growth rate. In 2014, the Quebec Anime Committee became the Otakuthon Cultural Society and continues to manage the convention to this day. In 2018, Otakuthon started offering VIP passes called Premium Badges. A badge mailout option was also introduced to
