Haim Saban brought us the Mighty Morphin Power Rangers, then merged his company, Saban Entertainment, with Rupert Murdoch's Fox Kids Network, and together acquired the Fox Family Channel. Disney bought Fox Family in 2001 for $5B, netting him $1.7B.
Today Haim chairs Univision, which he and a group of private equity investors purchased in 2007 for $13.7B. The network filed to go public in July and could be worth as much as $20B. Haim also formed Saban Capital Group, which has a real estate arm that focuses on GSA office space, retail, and self-storage.
