The rebranding project, which starts on February 15 for the flagship Nickelodeon channel, will include a completely new network logo.
Replacing the previous 'splat' symbol, the new logo will be a "simple, bold and timeless typographical execution which retains a link with the network's heritage while giving it a more contemporary feel".
The branding will be implemented on the TV channel, along with all related online platforms, consumer products and theatricals. Sister channels Nick Jr, Nick Jr 2, NickToons and NickToons Replay will also take on the new logo and branding during the second quarter.
Following the rebranding, the entire Nickelodeon global network will carry the same logo and on-air brand identity for the first time ever.
Nickelodeon UK introduced the 'splat' in 2003 to represent "how kids felt about rules, authority and being tidy", but the new logo is designed to "work everywhere, and play well with others".
"The channel rebrand signals a new global focus for the network; and an extremely exciting time for Nickelodeon," said Nickelodeon UK vice president of creative Peter Drake.
"The look is fresh, contemporary and addresses the needs of our audiences in a more relevant way. This simple and succinct execution offers a consistent stamp of approval which allows our characters, brands and properties to shine through - and do the talking. It has a contemporary feel and effectively enables us to leverage the power of our brands globally."
Last week, Nickelodeon UK also revealed plans to revamp its flagship pre-school mini-sites under the Nick Jr's brand to offer better structure and navigation.
