Tataranowicz was in charge of both Marvel Films Animation and New World Animation during this period. News Corporation subsidiary (1996) News Corporation/Fox Entertainment Group acquired New World Entertainment, along with New World Animation and Marvel Films Animation for $2.5 billion in August 1996. At the same time, Saban Entertainment secured the rights from Marvel Entertainment Group for Captain America, Daredevil, and Silver Surfer, and additional characters to be developed into four series and 52 episodes over the next seven years. Fox Children's Productions and Saban Entertainment merged to form Fox Kids Worldwide, a holding company and joint venture, in November 1996, while Fox retained ownership of New World Animation. Postscript Fox Family Worldwide and its assets, including the Marvel Productions library and Saban Entertainment, were purchased by The Walt Disney Company for $5.2 billion in July 2001, with Saban Entertainment renamed to BVS Entertainment in October 2001. After getting its 2002 profit participation statements for the Marvel Productions library, Marvel Enterprises sued The Walt Disney Company over royalties in August 2004 after Disney would not open their books. This was followed by a November 2004 suit which claimed that the purchase of Fox Family did not transfer the shows' copyrights to Disney as the purchase was done without Marvel's approval. As part of both suits, Marvel claimed library income concealment and failure to exploit the characters. On August 31, 2009, Disney acquired Marvel Entertainment for $4 billion, reunifying the Marvel Productions library and Marvel Entertainment under the same corporate banner. Disney then sold the Power Rangers franchise – which was included in the Fox Family acquisition and originally part of the BVS library – to Saban Brands in 2010; that franchise, since 2018, is currently owned by Hasbro. After Disney's acquisition of 21st Century Fox on March 20, 2019, the Marvel Productions and Fox Kids/Saban Entertainment libraries reunited with the New World Animation library.
