Little Baby Bum

Little Baby Bum (also known as LBB and LittleBabyBum) is a British children’s YouTube show which specializes in 3D animated videos of both traditional nursery rhymes and original children's songs. It was acquired by Moonbug Entertainment in 2018. Beginning in 2011 UK-based Derek Holder and his wife, Cannis Holder, designed videos based on classic nursery rhymes, but with a modern aesthetic. Little Baby Bum is also available in Spanish, Brazilian Portuguese, Italian, Russian, Polish, German, French, Chinese and Japanese. 
History.
Little Baby Bum was created to support kids' development of language through the means of song and repetition. Derek and Cannis uploaded their first video, Twinkle Twinkle Little Star, to YouTube on 29 August 2011. This was followed up, four months later, with their second upload, Baa Baa Black Sheep, a more complex and slightly longer video.
Little Baby Bum's popularity increased after the release of its 2nd compilation of videos which was approximately one hour long. To create a one-hour-long video they combined individual videos into long-form videos. The rationale behind this change was so that "parents wouldn't have to keep pressing the play button after each video had finished."
The OpenSlate company published a list of YouTube’s 10 most profitable channels of 2014, ranking Little Baby Bum in 4th place with 270 million views and $3.46 million in earnings.
In June 2018, LBB announced an upcoming live show tour in 30 cities throughout the UK.
In September 2018, Little Baby Bum was bought by Moonbug Entertainment for an undisclosed sum. By the time of the purchase, LBB had accumulated 16 million subscribers and about 23 billion views across Netflix, Amazon, and YouTube. 
In April 2020, Moonbug signed a deal with Chinese video platform Xigua Video, to host the show on its platform in China.

Merchandise.
LittleBabyBum signed a licensing deal to launch a set of plush toys of its main characters, extracted from the traditional English nursery rhymes, like Incy Wincy Spider and Baa Baa Black Sheep.

The plush toys went on general release on 18 May 2016.
