People more savvy of the industry may realize that most of the company's current VA's have worked at Central Park Media before (and this includes Dan Green as well); CPM distributed uncut productions mostly for pre-teen to older audiences, such as Revolutionary Girl Utena among others.
Creator Killer: Almost subverted byYu-Gi-Oh!; TV Tokyo and NAS tried to yank the license, and 4Kids ultimately prevailed within the year, but the damage had been done, and they still ended up selling the rights to Konami for all Yu-Gi-Oh!-related merchandise. While the production unit was reformed by Konami as 4K Media, the main company was reformed as 4Licensing Corporation and plenty of their assets were sold to Saban, many of their units were shut down and the company is now a shell of its former self. Played straight with their dub of One Piece, which effectively solidified the company's then-brewing hatedom.
Keep Circulating the Tapes: Without any of their notable assets, some of the 4Kids dubs of anime have not seen a re-release in some form. While some of their old properties have avoided this by being aired on Vortexx, that block met its end in September 2014, killing even that method. Heck, One Piece was redubbed by Funimation, which renders the 4Kids episodes that weren't released on DVD harder to find, even though the first 52 episodes can be found cheap.
After their contract with FUNimation was terminated for reasons still unclear, 4Kids shows stopped showing up on the home video market. The one exception was Pokemon, whose home video rights remained with Viz. Dinosaur King did turn up on DVD through Shout! Factory, but it didn't sell well enough to justify the company working with them again. After 4Kids sold off their assets, Yu-Gi-Oh! did get a revival on DVD through Cinedigm (formerly NEW VIDEO Group), but it's unknown if any other 4Kids shows will be released to home video through the company. Until then, we have TV rips and foreign DVDs to rely on.
According to Maddie Blaustein, 4Kids apparently DID dub the notorious episode of Pokemon with the seizure-inducing flashing lights. However, despite the lights being slowed down to "safe levels," the Japanese refused to let them air the episode, and the dub has never been discovered.
4Kids went back and dubbed the previously skipped "Beauty and the Beach" episode of Pokémon (the one featuring James cross-dressing with inflatable boobs) with the Orange Islands episodes (with the aforementioned scene cut). However, it only aired once, and is not on DVD. TV rips can be found fairly easily online though.
As of 2015, Discotek Media has got the rights to the 4Kids dub of Sonic X, and will start making DVD and Blu-ray re-releases!
Missing Episode: They did this to some of their dubbed anime. Yu-Gi-Oh! and the subsequent Sequel Series had a few, but ther dub of One Piece is infamous for throwing out entire story arcs. This, combined with 4kids' refusal to release uncut versions of their shows (for the most part), not only created Plot Holes, but made it so that these episodes would only stop being missing once Funimation got the rights.
4Kids was known for paying its actors very well (at least in relation to other dubbing studios). This is why you'll never hear any NYC voice actor express regret for working on a 4Kids series. The scripts may be crap, and the editing jobs may be a joke, but at least you're well-compensated for it.
Though this likewise seem to be their business philosophy as well. The heads of the company were only interested in how profitable a series could be rather then the quality of their products and the fandom of properties. And that's if they were even interested in the property at all (for example, they actually didn't want One Piece, just Tokyo Mew Mew. But Toei, wanting the anime to be shown in America as soon as possible, forced them to take it as part of the deal. As such even though the series was a major hit in Japan and had more then enough of a sizeable audiene in the west the profit from. They put the barest minimum of work into the dub as they truly didn't care about owning the series. Some even speculate that they were purposefully trying to lose the license via self-sabotage).
No Export for You: Due to their practice of making YouTube block certain videos from being played outside the U.S & Puerto Rico.
Star-Derailing Role: While the legal mess with Yu-Gi-Oh! may have proved a Creator Killer, their dub of One Piece was what brought down their reputation. That reputation wasn't spotless before, but it would never fully recover after that. The aforementioned legal mess was simply the final nail in the coffin.
What Could Have Been: During their final years, 4Kids was actively trying to undo the damage they did by setting up their own legal streaming site with uncut episodes, even partnering with Funimation and Crunchyroll, as well as proudly referring to their properties as "anime". Had they been able to continue without the legal issues, Toonzai could have very well been a spiritual successor to daytime Toonami, serving as a gateway to anime for children, while not alienating older fans.
