In 2002 the first attempt to hold an anime convention in Pittsburgh, Takocon, failed due to a booking problem at the Pittsburgh Marriott City Center and the lack of time to acquire additional space. In 2003, the first Tekkoshocon was organized by Rebecca Roach and occurred at the Wyndham Pittsburgh Airport. In 2004, the convention moved to the Pittsburgh Marriott North and became three days. From 2005 to 2007 Tekkoshocon was held in the Pittsburgh ExpoMart/Radisson Hotel Pittsburgh, but due to unexpected demolition work, Tekkoshocon moved to the Radisson Hotel Pittsburgh Green Tree for 2008.
