The first Animethon was a one-day event that allowed people to view different Japanese anime movies and television shows within two classrooms at Grant MacEwan.

It was not until Animethon 11 that the festival grew to utilize the entire university campus for events, artist alley, education panels, and a large vendor hall.

As such, the steady increase of numbers in attendees to Animethon has allowed for various vendors to expose themselves to a unique group of people both young and old.

[5] Animethon has experienced several years of consecutive growth in attendance while increasing their scope to include musical guests from Japan such as Flow, ROOKIEZ is PUNK'D, Yoko Ishida, Kanon Wakeshima, An Cafe, and Ladybeard.
