In April 2003, Nickelodeon began using its famous splat design as its main logo in the United States. After this, all other Nickelodeon international channels began using it as its main logo and the other morphing logos were used on small occasions. The UK was the last to rebrand to this, in September 2005.
In February 2009, Viacom announced that Nickelodeon would switch from its bubble writing-like capital letter text to a simple lowercase text. The United States rebranded to this look in September that year. Central and Eastern Europe were the last to rebrand to this design, in July 2011. Nickelodeon Arabia did not get a chance to rebrand, as it was shut down in October that year.
