The company is known for owning the largest independent library of children's television programming,[6] including the assets of acquisitions such as Cookie Jar Group, Epitome Pictures, and Wildbrain Entertainment among others, distribution rights to the Jay Ward Productions and Ragdoll Productions libraries[a], and a stake in the Peanuts franchise.

In May 2006, the Toronto-based Decode Entertainment merged with the Halifax-based Halifax Film Company as DHX Media, which went public on the Toronto Stock Exchange (TSE) and the London Alternative Investment Market (AIM).

DHX's then executive chairman Michael Hirsh stated that the offerings were meant to leverage the company's library and the growth of digital distribution in the children's television market.

In November, DHX purchased 117 children's and family titles from US distributor Echo Bridge Home Entertainment.

Other shows in the purchase included Lunar Jim, Beast Wars: Transformers and Cookie Jar's Emily of New Moon.

[25] In April 2015, Corus Entertainment announced that it had acquired Canadian rights to the program library of Disney Channel and its associated brands as part of a deal with the Disney–ABC Television Group; DHX's existing deal with Disney, which covered programming across the four DHX Television services, ended in January 2016.

[30] Also that month, DHX established a development deal with Mattel to co-develop and handle global sales for content in the Little People and Polly Pocket franchises, as well as HiT Entertainment properties owned by them such as the Bob the Builder and Fireman Sam franchises, including television and digital video programming.

The purchase gave DHX full ownership to the Strawberry Shortcake franchise and, more prominently, an 80% majority stake in Peanuts Worldwide.

DHX's debt had increased following the Iconix acquisition, and the company reported a net loss of CA$18.3 million during its fiscal fourth quarter.

[36] On May 14, 2018, DHX announced that it would sell a 39% stake (approximately 49% of its total ownership) in Peanuts Worldwide to its Japanese licensee Sony Music Entertainment Japan for US$185 million.

[48] WildBrain announced its intent to acquire Toronto-based animation studio House of Cool for CA$18.3 million on March 29, 2023.

As part of the deal, House of Cool co-founders Wes Lui and Ricardo Curtis joined WildBrain as co-general managers of the studio.

[51] On December 18, 2024, WildBrain announced that it would sell a two-thirds majority stake of its television operations to IoM Media Ventures, pending CRTC approval.
