List of Episodes

(This list represents our best understanding of the show's broadcast history at this time. The "OSI74 seasons" began with season 12, and as of this edit, records of seasons before that are incomplete and of indeterminate accuracy, even to members of the production; there are missing and lost episodes, and the broadcast order may not be accurate.)
(Some episodes that appear more than once have special designations such as "(2016 Version)" or "(OSI Version)" which reflect that the episode had aired previously, but was re-edited or remastered from its originally broadcast version.)
