The channel initially launched on 17 September 1993 as a larger pan-European feed, serving the UK market along with Western and Northern Europe.

As a result of Turner purchasing MGM's Cartoon and Film library, Warner Bros. pre-1948 content was also acquired, including early Looney Tunes and Merrie Melodies shorts.

The Checkerboard branding package was developed by Hatmaker Studios,[22] now merged and part of its sister company - Corey, McPherson and Nash.

[13] From 15 November 1998, Cartoon Network was part of ITV Digital's channel package, airing 24 hours a day until the service collapsed on 1 May 2002.

During the late 90s and the early 2000s, Turner Entertainment Networks International started localising their channels to suit different audiences across different countries around Europe, Middle East and Africa.

Designed by Brand New School, it makes heavy use of a black and white checkerboard motif, as well as various CMYK colour variations and patterns.

On 1 April 2014, Cartoon Network's DOG moved back to the top-right corner and a new Next banner using graphics from the Check It 3.0. branding package was introduced.

[38][39] Mega Mondays was the name of Cartoon Network's new episodes programming block for three years before being discontinued in July 2017.

[41] In February 2016, Cartoon Network used graphics from the Check It 4.0 branding package for the first time on a new episode promo for Transformers: Robots in Disguise.

[43] In April 2016, Cartoon Network signed a deal with Sky for exclusive on-demand boxset rights for a selection of its animated shows.

[44] In November 2016, Cartoon Network won two PromaxBDA UK awards for their Where's Ice King and Weetabix Weetabuddies television campaigns.

Like the UK, the Czech Republic has minimal broadcasting regulations and was chosen for EU licensing purposes as WarnerMedia's HBO had substantial operations located in the country.

[48] Between 27 and 28 July 2024, Virgin Media UK introduced a kids block called “Kids Summer of Sport” for one day each on its Showcase and Kids channels to show programming from Cartoon Network and Cartoonito, including some shows that ended on them, including Teen Titans Go!, Scooby Doo and Guess Who?, Fireman Sam, Apple and Onion, Looney Tunes Cartoons, Batwheels, Craig of the Creek, Mr Bean: The Animated Series, Lucas the Spider, We Bare Bears, The Tom and Jerry Show, Bugs Bunny Builders, Clarence, Grizzy and The Lemmings, and Masha and the Bear.

Dragon Ball Z had already been airing on Cartoon Network since March 2000, and had been attracting very good ratings, which may have contributed to the decision to launch Toonami in the UK.

As time went on, Toonami started to shift away from Japanese anime and action programming, eventually morphing into CN Too.

Additionally, the block's name would change to "Mince Pie Mondays" every December, sporting a more festive look and airing Christmas specials to boot.

Despite only lasting around four months, the block had a large variety of shows rotating in and out of premiere slots, including Adventure Time, The Amazing World of Gumball, Ben 10, Clarence, Cloudy with a Chance of Meatballs, Mighty Magiswords, Ninjago: Masters of Spinjitzu, OK K.O.!

Let's Be Heroes, The Powerpuff Girls, Regular Show, Steven Universe, Supernoobs, Teen Titans Go!, We Bare Bears, Uncle Grandpa, and Unikitty!.

[citation needed] On 1 March 2022, a Cartoonito block was launched, airing on weekdays from 9 am to 10 am (although it briefly extended to end at 11 am during the Spring-Summer of 2022).

CNX was carried in the 'Entertainment' section of the Sky programme guide, and was also available on cable Toonami launched in September 2003 showing action programming.

[59] The studio was named after Great Marlborough Street where Turner Europe, Middle East and Africa's headquarters is located.

Cartoon Network Europe has also been involved in other co-productions in the past such as The Cramp Twins, Fat Dog Mendoza, Robotboy, Scooby-Doo!

Mystery Incorporated, Elfy Food, The Happos Family,[61] Hero 108, Spaced Out, VBirds, Cult Toons, Taffy,[62] Best Ed, Chop Socky Chooks, Skatoony and The Heroic Quest of the Valiant Prince Ivandoe.

Those who could still receive the channels had a backup transmission played out, making people confused when Cartoon Network Too and Boomerang were showing episodes of The Flintstones at the same time.

These backups where played out with a scrolling message which said "We apologise for the disruption to this programme due to technical problems and we are trying to correct the fault.

Whilst most channels returned to the air within 5–10 minutes, it took longer for Cartoon Network Too to resume programming and it was also joked on various animation based forums by Toonami UK viewers, many of whom have made note of their disdain for the direction in which Turner took the brand in the UK, that the backup transmission was more entertaining, purely due to the lack of live action programming aired during the outage.

Animated shorts produced by the studio include The Furry Pals, Mutant Moments, Hamshanks and the Himalolly Railway, Elliot's Zoo, Pinky Malinky and Verne on Vacation.
