Yeah, the old Cbeebies logo lasted 21 years, 2002 to 2023. Nickelodeon's splat logo is probably the only one in kids TV that's lasted longer, as it was used in the US from 1984 to 2009, 25 years. However, Nick only launched in the UK in 1993 so it was only used for 17 years here (until 2010).

Cartoon Network's original logo was used for quite some time as I recall too.
