Contender Entertainment Group  was the original Company that made Peppa Pig. After Season 1, credit was then shifted to Rubber Duck Entertainment, the children's division of Contender. 

On the DVDs, the Contender Logo is still present.

In 2007 the Company was sold to Canadian company E1 Entertainment and rebranded into E1 UK in 2010. In season 3, Peppa Pig used the E1 entertainment logo.
