Here's a breakdown of official and unofficial sources:

Official

 * Alex Hirsch
 * Disney
 * Hirsch's production team

Unofficial

 * Zap2it
 * TV guides (as these are owned by the company taking the information from Disney's schedule to present a guide to channel viewers)
 * Online TV guides (again, these are owned by the owners of the site, rather than Disney or Hirsch)
 * IMDb (not just unofficial, but unreliable)
 * TV.com (also unreliable, user generated content just like IMDb)
 * Other wikis (unreliable too, their information is their own, and they might say false information as anyone can edit it
 * Wikipedia (as well as unreliable, they get their information from Zap2it, as Wikipedia relies on secondary sources for notability reasons, as listed, Zap2it is unofficial too)
