Tooniverse broadcasts an extensive collection of programs that encompasses cartoon shows, movies, and popular content targeted across all age groups, including children, teenagers, and adults.

Up until its launch, cartoons were normally restricted to the 5-7pm timeslots on terrestrial television networks, as well as weekend mornings, per the law.

[2] As of 2009, the channel is operated under CJ ENM, which has steadily preoccupied the 5th place in the cable TV viewing market share as the viewership rate has gradually increased since 2000.

However, in November of that year, On-Media (now CJ ENM) unilaterally refused to renew the contract, and was exclusively broadcast through cable TV from January 1, 2003, to August 31, 2011.

[8] The Starleague professional StarCraft: Brood War broadcasts began as a program on Tooniverse before being spin-off onto a dedicated gaming channel, Ongamenet.

Meanwhile, it was announced that Tooniverse would air a pilot episode titled The Haunted House (신비아파트 [ko]).

[citation needed] In 2016, Tooniverse created the first season of The Haunted House: The Secret of the Ghost Ball.

[11] In the same year, the show returned with a season 2 that was named The Haunted House: The Birth of Ghost Ball X.

[19] In August 2022, Tooniverse announced that the show is going to be aired on Jujutsu Kaisen on September 23, 2022, as well aired on Erased, That Time I Got Reincarnated as a Slime, Sword Art Online and other anime to the channel under the TooniTeen (투니틴) programming block at every Friday & Saturday night from 10 p.m.
