4Kids Entertainment is an American company, responsible for the production of the English-language version of the Yu-Gi-Oh!, Yu-Gi-Oh! GX, Yu-Gi-Oh! 5D's and Yu-Gi-Oh! ZEXAL animes since 2000. They also handle English production for a number of other anime series as well as creating original series.
4Kids Entertainment introduced 4Kids TV, then called the FoxBox on September 14, 2002 after Fox Kids was dissolved following the purchase of Fox Family Worldwide by Disney. The block was re-branded 4Kids TV in January 2005. 4Kids Entertainment is wholly responsible for the content of the block and collects all advertising revenues from it - making it one of the main outlets in the United States for 4Kids licenses and properties.
Many of the licenses distributed by 4Kids Entertainment, and presented on 4Kids TV are managed by 4Kids Productions, which is a wholly owned subsidiary of 4Kids Entertainment. First launched in 1992, 4Kids Productions deals primarily with television, film, home video, and music licenses, and manages the programming for 4KidsTV.
In September 2008, 4Kids entertainment bought a block of programing on the CW, and it was entitled the CW4kids. This block was run at the same time as its other block on 4KidsTV. Later, its block on Fox ended and now it only broadcasts on the CW. The many shows from its 4KidsTV were moved online to its website. All 5 seasons of Yu-Gi-Oh!, as well as many Yu-Gi-Oh! GX, Yu-Gi-Oh! 5D's and Yu-Gi-Oh! ZEXAL episodes are available for viewing on their website. Many episodes of 5D's and ZEXAL are available in Japanese with English subtitles on their Toonzaki website. Currently, 4Kids Entertainment broadcasts Yu-Gi-Oh! ZEXAL.
On March 30, 2011, TV Tokyo planned to terminate all rights to Yu-Gi-Oh! from 4Kids and filed a lawsuit on "Illegal Transaction". The full details is on this newspost. According to a source on voice actor Dan Green's Facebook fanpage, the termination is not official until the court makes it valid which 4Kids and TV Tokyo are still fighting over in court.
In June 2012, 4Kids sold the rights to their current assets, including the Yu-Gi-Oh! anime franchise, in a joint agreement, part to Konami, and part to Saban Brands. Konami would recieve YGO rights, and Saban would gain the rights to air what was previously the Toonzai saturday morning block, and all of the other programs associated with it, including Yu-Gi-Oh! ZEXAL. 4Kids had gotten the rights to dub the series up until Episode 41, and the rights transferred mean Konami will start dubbing up to that point and will then decide whether to dub more episodes.
The new block Yu-Gi-Oh! ZEXAL will premiere on, Vortexx, will make its world premiere on August 25, 2012. One more new episode, the dub of Episode 25 of ZEXAL, will air on August 18, 2012 at 11:30 AM EDT, marking 4Kids' final broadcast on a saturday morning block, for the time being, and the final episode of Yu-Gi-Oh! to air on a 4Kids-produced network.
The company has received much contempt from fans of series they have dubbed, due to the changes made to these series. This usually involves the complete changing of the music score and sound effects (with much of the 4Kids dub sound effects being made from or sounding like the original Japanese sound effects). It also involves censoring and Americanizing content to suit an English speaking and younger audience demographic (e.g.; Adding the Shadow Realm or a purple fog to the death of Carly). Even removing written language characters (Japanese and English) or replacing them with unreadable content. They also cut out some scenes that aren't bad at all, this is mainly done for time constraints but also for unknown reasons. This is partly due to FCC regulations for American cartoons. More controversy has made by the company has caused an outcry from fans because of their treatment towards with both Yu-Gi-Oh! GX and Yu-Gi-Oh! 5D's, both of which had many episodes skipped, leaving many questions unanswered, especially the 5D's series. Both series were left incomplete, as neither of them had their final seasons dubbed.
