A number of Season One episodes were re-screened as The Clone Wars: Decoded. These featured pop-up boxes containing trivia and behind-the-scenes information relating to each episode. Some were presented as in-universe annotations by characters in the episode (as though accessed from a historical archive of events during the Clone Wars), while others feature real-world references, or references to information the character would have no knowledge of. Therefore, it is doubtful that all the annotations should be considered canonical. Decoded began on May 1, 2009, and continued to run every Friday at 9 p.m. ET/PT, the regular time slot for the series. Decoded continued until the October 2, 2009, premiere of Season Two. In total, seventeen Decoded episodes were aired—the first fourteen episodes, plus episodes sixteen, eighteen and twenty-two.
