To promote CNX, six people attempted to break the world record for continuous TV watching, set at 46 hours, 30 minutes, and 50.91 seconds.

[4] At the time, Turner was in negotiations with Telewest to add the channel to their Active Digital cable service, and was soon added on 15 January 2003.

[8] CNX did not function like Turner's other kids channels, instead operating as a general entertainment network with children's programming during the day and more adult programming at night, which included martial arts movies, adult-oriented animation like the Adult Swim originals, and dramas like The Shield, Birds of Prey, Sports Illustrated Swimsuit Issue and action film Point of No Return.

[14] On 6 March 2006, Toonami changed its focus from action cartoons to entertainment in general, as the channel moved to Sky 602 and began airing five live-action shows: Backyard Science, Parker Lewis Can't Lose, Stencil, Hangin' with Mr. Cooper and Life with Derek.

On the night of 26–27 July 2006 Cartoon Network Too, along with its sister channels, suffered a major technical fault due to a power cut in Soho, London, owing to the 2006 European heat wave, with thunderstorms taking full force overnight.

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.

While 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.

There were also bumpers in the Sensor Room showcasing the latest games, movies, and shows, with TOM displaying the awkward and dorky personality he was known for on the US Toonami.
