Even though it debuted some time after the manga, the anime quickly caught up, since one anime episode usually covers one or two manga chapters. To prevent overlapping, the anime's producers tend to organize content from the manga chapters into long, uneventful sections followed by short bursts of action, sometimes adding filler content in between. By the time the last canonical arc of the anime concluded, it was quickly gaining on the manga and consequently switched to anime-only filler episodes to allow the manga to broaden the gap once more. Most of the filler episodes are stand-alone stories, with a few being part of arcs that are several episodes long. The filler episodes lasted for 85 episodes, the duration of the first series. After the series moved back into manga-adapted episodes, it was renamed Naruto: Shippūden (疾風伝, Naruto: Shippūden? lit. Hurricane Chronicles). The new series premiered on February 15, 2007.
The anime generally remains true to the manga, usually changing only minor details (causes of death, loss of limbs, and other injuries have been lessened in the anime) or expanding on parts skipped by the manga. The filler arcs, though unreferenced in the manga (save for a few scant scenes), deal with the breaks between story arcs, most prominently the period between the mission to retrieve Sasuke and Naruto's departure from Leaf Village at the end of the original series. The filler arcs also often shine the spotlight on minor characters that have received little narrative attention otherwise.
New episodes, animated by Studio Pierrot, air weekly on TV Tokyo in Japan during the Golden Time slot (Japan's equivalent of prime time in the US). As of October 5, 2006, it shows on Thursday nights. The series has also spawned four movies, Naruto the Movie, Naruto the Movie 2, Naruto the Movie 3, and Naruto: Shippūden the Movie. The first three are available on DVD,while the fourth one was released on August 4th 2007.

In the US, Naruto maintains a TV-PG rating in every episode. Most usually are rated TV-PG-V for episodes with heavy violence, while others (usually with Jiraya) are rated TV-PG-D.[6] References to alcohol, Japanese cultural differences, mild language, mild sexual situations, and even blood and death remain in the English version, though reduced in some instances.[7] Other networks make additional content edits apart from the edits done by Cartoon Network, such as Jetix's more strict censoring of blood, language, smoking and the like. So far, only one episode, the "lost OVA", has received a TV-Y7-FV rating, but this was likely due to Cartoon Network neglecting to update the rating for usually in the timeslot that this special ran in TV-Y7-FV programs ran. Repeated viewings (such as the on August 8, 2007) have listed the special as TV-PG-V, As did all commercials for the special.
