I'll list shows on each page chronologically rather than alphabetically. I'll try to list dates that shows aired on a particular network, but when a show aired on multiple networks (particularly in different countries) I may only know one set of dates, and it may be for the wrong network. However, sometimes I will be able to provide different sets of dates for different networks, if I list a show on more than one network and Wikipedia provides both sets of dates. I'll also let you know what country networks are from. (Unless otherwise noted, networks on the list are from the USA.)

Adult Swim
Fuji TV (Japan)
Sci-Fi Channel
