As a Japanese version of the eponymous television channel in the United States, Cartoon Network broadcasts original series from its U.S. counterpart, as well as several Japanese animated media and other non-Japanese programs.  An amount of non-Japanese programs are also available in English via secondary audio feed.  It is one of few versions of Cartoon Network outside U.S. that broadcasts its programs in High Definition.

The game was only released and made available in Japan.  It was preceded by "Rockman EXE Phantom of Network".  The game introduces a new character named Cerise (シェリス , Sherisu ) , a Netopian. The Powerpuff Girls is an American animated superhero action-comedy television series and a reboot of the Cartoon Network series of the same name.  It was first announced in June 2014; a year later, it was announced that it would feature new voice actors for the main characters.

Lois Patrice Griffin (née Pewterschmidt) is one of the main characters of the American animated television series "Family Guy".  She is voiced by writer Alex Borstein and first appeared on television, along with the rest of the family, in the 15-minute short on December 20, 1998.  Lois was created and designed by series creator Seth MacFarlane.  MacFarlane was asked to pitch a pilot to the Fox Broadcasting Company based on "Larry and Steve", a short he made which featured a middle-aged character named Larry and an intellectual dog, Steve.  After the pilot was given the green light, the Griffin family appeared on the episode "Death Has a Shadow".

Animation Collective produces the series.  It originally aired on September 29, 2006 on Cartoon Network in the United States, airing at 9:30 am ET/PT, but has been pulled from the schedule as of February 5, 2007.  The show features a very imaginative five-year-old child named Ellen who has adventures in a hotel her parents own approximately 40 miles from Tonopah, Nevada named the Emerald Acres (hence the show's title). Rudolph the Red-Nosed Reindeer is a 1964 Christmas stop motion animated television special produced by Rankin/Bass Productions and currently distributed by Universal Television.  It first aired Sunday, December 6, 1964, on the NBC television network in the United States, and was sponsored by General Electric under the umbrella title of "The General Electric Fantasy Hour".  The special was based on the Johnny Marks song "Rudolph the Red-Nosed Reindeer" which was itself based on the poem of the same name written in 1939 by Marks' brother-in-law, Robert L. May.  Since 1972, the special has aired on CBS, with the network unveiling a high-definition, digitally remastered version of the program in 2005.  As with "A Charlie Brown Christmas" and "How the Grinch Stole Christmas", "Rudolph" no longer airs just once annually, but several times during the Christmas and holiday season on CBS.  Unlike other holiday specials that also air on several cable channels (including Freeform), "Rudolph" only airs on CBS.  It has been telecast every year since 1964, making it the longest running Christmas TV special in history.  2014 marked the 50th anniversary of the television special and a series of postage stamps featuring Rudolph was issued by the United States Postal Service on November 6, 2014.

It originally aired on the Fox network in the United States on February 9, 1997.  In the episode, "The Itchy & Scratchy Show" attempts to regain viewers by introducing a new character named Poochie, whose voice is provided by Homer.  The episode is largely self-referential and satirizes the world of television production, fans of "The Simpsons", and the series itself.  It was written by David X. Cohen and directed by Steven Dean Moore.  Alex Rocco is a credited guest voice as Roger Meyers, Jr. for the third and final time (having previously provided the character's voice in "Itchy & Scratchy & Marge" and "The Day the Violence Died"); Phil Hartman also guest stars as Troy McClure.  Poochie would become a minor recurring character and Comic Book Guy's catchphrase, "Worst episode ever", is introduced in this episode.  With "The Itchy & Scratchy & Poochie Show", the show's 167th episode, "The Simpsons" surpassed "The Flintstones" in the number of episodes produced for a prime-time animated series.
